— | The laser module is an LED with a cylindrical copper heatsink for cooling, which is used as the emitted component. The module can be used both in a security system using an outgoing beam as an obstacle, upon crossing which an alarm is triggered, and in domestic projects. The module board is designed based on the KY-008 laser diode and auxiliary passive elements, to ensure the stable operation of the laser. The advantages of the module are: consumption of 30 mA of current and the ability to consume power directly from the Arduino board. The module generates red radiation in the range of 650 nm with a constant power of 2 - 5 mW. The light spot of the laser can extend to a distance of up to 14 meters. The radiation intensity of the KY-008 laser module is controlled by current. When the threshold value of the passing current is exceeded, the intensity of the radiation of the laser LED increases sharply, respectively, at low currents, the laser emits like a conventional LED. The module is connected using a common I2C serial interface that works in conjunction with the Arduino Uno or other microcontrollers. Power is connected to the module from contacts +5V and GND. You can supply power to the module from an external power source or from the ports of the Arduino Uno. The S output serves as a contact for transmitting control signals to the microcontroller. When working with the module, you must be careful not to direct it into the eyes, in addition, during long work, the laser heats up very much, especially at high intensity of the passing current.

— | The Basic Learning Kit is a multifunctional expansion board that is designed for beginners learning the Arduino platform, but can also be used to create various projects that require a large variety of sensors and modules. Almost all additional Arduino modules can be connected to this board. The following components are located on the expansion board: 4 LEDs, a seven-segment four-digit display, an active buzzer, a trimmer resistor, 4 buttons (one of them is for resetting the Arduino board system, and the remaining three can be used to navigate through the device menu, change the threshold value, activate sensors etc.). An active buzzer is designed to reproduce sound signals. The buzzer is active as there is a built-in generator in its case. When current is applied to the buzzer, its relay coil excites a magnetic field. Under the action of a magnetic field, the relay contacts open. After opening the contacts, the current in the circuit disappears and the magnetic field disappears, after which the springs return to their original position. The process is then repeated as long as current is applied to the circuit. Due to the vibrations of the armature, air vibrations appear, which reproduce the sound of the buzzer. An active buzzer can be used as a siren to notify you of any activity. The 10 kΩ trimmer is a passive electronic component for fine tuning device parameters. With this resistor, you can change the volume of the buzzer, the sensitivity of the sensors, the brightness of the LEDs, LED display, etc. Also on the expansion board there are contacts for connecting additional external modules and sensors. The Bluetooth module, the APC220 radio module and the SYN6288 speech synthesis module are connected to the contacts located near the seven-segment indicator. Pin assignments: SET: module setting AUX: module mode TXD: signal receiving line RXD: signal transmission line EN: enable VCC: supply voltage GND: ground An IR sensor is connected to U4, and an LM35 (analog) or DS18B20 (digital) temperature sensor is connected to U5. Pin assignments: VCC: sensor supply voltage VOUT: data line GND: ground The following components can be connected to the pin terminals: DHT11 and DHT22 humidity and temperature sensors, SG90 and MG90S servo drives, etc. GND: ground VCC: supply voltage VOUT: data line The connected sensors and modules correspond to the following pins on the expansion board: D2: IR (infrared sensor) D3: sound emitter D5, D6, D9: external sensors D10 - D13: LEDs A0: trimmer A1 - A3: tact buttons A4: LM35 and DS18B20 temperature sensors A5: analog sensors The circuit is easy to use and minimizes the risk of failure of the elements if they are connected incorrectly. There are also 2 jumpers (J1 and J2) on the expansion board. When connecting an analog LM35 sensor, jumper J1 is removed, and when connecting a digital sensor DS18B20, both jumpers remain in place.

— | This module is designed for switching AC voltage. Often, a solid state relay serves as an on /off switch for high-power circuits. Using this module, you can connect a control circuit, control electric motors, maintain one temperature in industrial production processes, etc. The module board is designed based on 2 Weiba solid state relays, 2 LEDs (indicate the state of the relay), and other auxiliary components that ensure the correct operation of the module. A solid state relay has the same functions as an electromagnetic one. The main feature of this relay is the absence of mechanical parts, which ensures silent operation of the module and a longer period of its operation. Due to the fact that the isolation is provided by an opto-triac, it is not possible to switch a DC load with this relay. The solid state relay consists of 4 circuits: primary, trigger, switching and protection. The first circuit is designed to receive the control signal and provide isolation between the input and output circuits. The trigger circuit switches the relay output, and the switching circuit energizes the load. The last circuit is designed to protect the relay from possible damage. The load can be a device with a current of up to 2 A, where the AC voltage range is in the range from 75 to 264 V. Also, the features of a solid state relay are: small dimensions, built-in noise protection, high speed and long service life.

— | The HW-040 (KY-040) module consists of a rotation angle sensor (encoder) and auxiliary electrical components for stable operation of the sensor. An encoder is a mechanical sensor that reports the angle of rotation, rotation speed and direction of the axis of various devices. This module can be used to control servos or stepper motors. The HW-040 module has 20 fixed positions per revolution. These positions represent a small click when the encoder axis is rotated. The rotation angle sensor has 3 outputs, which are designated (A, B, C). The principle of operation of the encoder is to change the positions of the switches. One switch is responsible for connecting pins A and B, and the second for pins B and C. Each change in the position of the sensor axis changes the states of the switches. In addition, the encoder is equipped with a button that works when the shaft is pressed. The button can be used to select menu items of the device or to change the sensitivity of the sensor.

— | The INA219 module is a digital sensor designed to measure current, voltage and power. The main advantages of this meter are: high accuracy of current and voltage measurements and small dimensions, which expand the scope of the sensor. The module can be used in systems where it is necessary to control current and voltage readings. The range of measured voltages of the sensor is from 0 to 26 V. The basis of the sensor is the INA219 chip, which reads the voltage on the shunt. After reading the data, they are stored in the registers of the microcircuit. The shunt resistance is 0.1 ohm. The resistive shunt is in open with positive power, which ensures that there are no potential shifts between GND and other devices. A 12-bit ADC (analogue-to-digital converter) is built into the microcircuit, with which the parameters are measured. Measurement data is transmitted via the I2C serial interface at up to 3.4 Mbps. It is connected to the SCL (clock passing) and SDA (data transfer) pins. You can also change the module interface address. To do this, you need to install jumpers on the marked pins A0 and A1 by soldering. Changing the board address allows you to create 4 combinations per I2C interface, so you can connect 4 similar modules. You can supply power to the module board using an external power source, from the Arduino board or other microprocessor device. Sources are connected to the sensor via the VCC and GND pins. To connect the measured power source, you can use the VIN+ and VIN- contacts or connect it using a terminal block. The polarity of connecting the power supply terminals is drawn on the board (on the right side - a negative charge, on the left - a positive charge). To further work with the sensor in the Arduino IDE development environment, you will need a library that can be downloaded. The module also includes a non-soldered pin connector and a terminal block. If necessary, they can be placed on the board using soldering.

— | The RGB SMD LED module RKP-RGB-LED5050 is designed to be used with devices using the ARDUINO platform (Arduino). At first glance, RGB LEDs look just like ordinary LEDs, but they actually have three LEDs inside: one red, one green, and one blue. By controlling the brightness of each one, you can control the color of the LED. There are two elements on the RGB-5050 module board: a three-color LED SMD 5050 and a 4-pin connector. The LED contains three crystals of red, green and blue colors. They can light up simultaneously or alternately. The SMD RGB LED module is used to indicate the operating modes of devices, to illuminate LCD indicators and keys. It is used in toys and complex entertainment equipment. Multi-color lighting provides a wide scope for design solutions, which is important in advertising, for decorating clubs, concert halls and during various public events. The original effect is created by highlighting water and ice sculptures. 3 color LED module for Arduino. Analog outputs on the Arduino use "pulse width modulation" to produce varying amounts of current. You can feed all three color inputs on the LED with a different PWM signal value in the range from 0 to 255, which will allow you to get almost any color out of 16,000,000 possible. Great for solderless breadboards.

— | The MAX6675 module, together with a thermocouple, allows you to measure the temperature of objects and the environment. Connects to a K-type thermocouple sensor. The sensor measures temperature readings in the range 0 - 1024 °C. But since the thermocouple body is designed for 600°C, the maximum temperature that can be measured is 600°C. The adapter can be used in a soldering station, boiler, digital thermometer, oven or in devices where temperature control is required. The temperature measurement module is based on the MAX6675 chip. The main task of the microcircuit is to convert the received K-type thermocouple signals into a digital temperature value. The sensor signal is sent to the operational amplifier of the microcircuit, and then it is processed by a 12-bit ADC (analogue-to-digital converter), after which the data is transferred to the microcontroller's memory via the SPI serial interface. There is no MOSI pin on the SPI bus, so the data from the chip is transmitted only to the controller. The main feature of the MAX6675 chip is the cold junction compensation function, which is implemented thanks to the built-in temperature sensor. The sensor is connected to the Arduino platform using the SPI interface through 3 pins. The SCLK pin is required to transmit the clock signal, CS is used to select the microcircuit, and information is transmitted through the D0 pin from the temperature sensor to the microcontroller device. 5V power can be supplied to the sensor from an external power supply, Arduino Uno board, or other microcontroller device. Power for the sensor is supplied to the VCC (+5 V) and GND ("ground") pins. The thermocouple terminals are connected to the clamp. The connection polarity is shown on the sensor board. The MAX6675 sensor library is not a standard Arduino IDE library, so you need to download it and install it yourself. Thermocouple and connecting wires are not included in the module package.
