— | This module is a PCA9685 12-bit PWM expansion board that can connect up to 16 servos. The PWM frequency is adjustable in the range from 24 to 1526 Hz. Also, using an additional module, it becomes possible to connect up to 62 boards or 992 servos in series. With this board, it becomes possible to develop both simple and complex projects. The module is designed based on the PCA9685 chip in the TSSOP28 package. The module board has 6 pins, where VCC is used to supply power to the board chip, GND is ground, and the V+ pin is supplied with voltage from the power supply. The SCL pin is the clock line and SDA is the data line. The OE pin is used to control the outputs. Using this contact, you can turn off the outputs, transferring them to one of the logical levels. The expansion board is controlled by I2C. The I2C interface is connected via the SCL and SDA pins. In case you need to use more than 16 servos, there are additional GND, OE, SCL, SDA, VCC, V+ pins on the board to which you can connect an additional module. After connecting an additional module, it is necessary to assign a unique address to it, since the base addresses of the boards are 0x40. The board address is indicated at outputs A0, A1, A2, A3, A4 and A5. You can assign a unique address using the address jumpers located in the upper right corner of the board. Servo drives are connected to 3 pins (V+, PWM and GND). The two V+ and GND outputs provide power (up to 6V) and the PWM output provides PWM signals. The power supply of the board and the PWM outputs is separate and can be 3 - 5 V. The PWM power can be supplied both to the V+ pins and to the terminals using the external power supply terminals. A filtering capacitor is installed on the board, which eliminates interference when the module operates with heavy loads. To work with the module in the Arduino IDE development environment, you need to download the library. A feature of this library is the control of servo positions using percentages.

— | FC-03 - module with infrared linear displacement sensor. The sensor is used in Arduino projects to determine the speed, rotational speed and count the impulses of the movements of different parts of the mechanism. The module board is designed based on the LM393 chip and the ITR9608 slot sensor. LM393 is based on two voltage comparators. The chip is used to compare two analog signals. The salient features of the LM393 are: low current consumption (0.45mA), available in a variety of packages and a wide supply voltage range. The ITR9608 is an optical slotted sensor into which an object is placed to read the number and frequency of rotations. An optical pair is the main element of the sensor. The ITR9608 package contains an infrared LED and a phototransistor, which are located opposite to each other. When an object appears in the gap between the elements that is capable of containing infrared radiation, the signals from the LED overlap and the transistor closes. If the transistor is closed, then the mechanical parameters are converted into digital signals at the output. You can also determine the frequency of rotation. To do this, an object with holes is placed in the slot of the sensor, which has a cutout of 5 mm. When the disc turns, holes appear in the slot. The encoder then converts the alternations into pulses, respectively the pulses into digital signals. The module has 4 outputs: VCC and GND, which are necessary to supply power to the module, D0 outputs digital signals, respectively, A0 is used to transmit analog signals. There are two LEDs on the board, where one signals the power supply to the module, the other LED is on until the object is located between the phototransistor and the infrared LED.

— | The FC-28 moisture sensor module is designed to measure soil moisture. The module can be used in projects for which it is necessary to read soil moisture data (automation of plant irrigation control, etc.) This module, like most sensors for Arduino, is designed on the LM393 comparator, which compares the signals at the output of the sensor. Also on the board is a potentiometer for adjusting the sensitivity threshold of the sensor. The FC-28 is designed around two sensors that provide soil moisture measurements. Moisture is determined using two probes that allow current to pass through the soil. When current passes, the sensor measures the resistance and ultimately measures the amount of water in the soil. The more water, the less resistance, respectively, if the soil is dry, then the resistance will be greater. The module is connected to the Arduino through 4 outputs (GND, VCC, D0 and A0). GND and VCC are used to supply power to the board with a value of 3.3 - 5V. A0 is an analog output that accepts analog values of 0 - 1023. D0 is used as a digital output to connect to the Arduino. The power supply to the module can be supplied from a microprocessor device or an external power source. There are two LEDs on the board. The blue LED indicates power supply to the module, respectively, the red LED lights up when a signal is transmitted to the microcontroller. After connecting the module to the Arduino, you need to place the sensor in the measurement environment. Then the written program code for the sensor in the Arduino IDE development environment must be loaded into the microcontroller's memory for the module and Arduino Uno to work together.

— | The FC-37 module is a high sensitivity humidity sensor and board designed based on the LM393 comparator. The LM393 chip processes and transmits the signal to the microcontroller in digital or analog form. This module can be used in projects where it is necessary that the device turns on when moisture interacts (in the detection of water leaks, in weather stations, etc.).

— | The non-contact sensor FC-51 detects objects in the range of distances from almost zero to the set limit without coming into direct contact with them. The sensor is intended for use when information about the distance to the object is not required, but only about its presence or absence. The registration distance limit depends on the setting. Sensor FC-51 has a discrete output. This is an optical sensor that registers an increase in the intensity of reflected infrared (IR) radiation in a controlled space. The change in the reflected radiation occurs due to the moving parts of the mechanisms or the movement of surrounding objects. FC-51 can be placed on a moving object to determine the position in the surrounding space. It is used to detect obstacles in the movement of wheeled and tracked machines. The sensor can become part of a visual aid for students in the field of control systems and automation. The device contains an IR radiation source and a photodetector. The radiation is reflected from an obstacle and is recorded by a photodetector. It transmits a signal to the LM393 comparator, which is configured to operate at a certain level of illumination of the photodetector. The comparator generates a low or high logic level signal at the output of the FC-51 sensor. Different reflection and absorption of radiation from different materials are used for the operation of the tachometer receiving unit. Let's say we have an engine. It is required to know the number of revolutions per minute of the motor shaft. FC-51 will help us out. It is enough to stick a piece of white paper on the flywheel, direct the sensor beam to the flywheel and get the tachometer receiving unit. To reduce the consequences of various interferences, the processing microcontroller accumulates data received from the sensor in a short period of time and averages it. The FC-51 sensor can also work in devices that do not have a microcontroller. The module is connected from 3 pins, where the VCC and GND pins are used to supply power to the module, and the received signal from the sensor is transmitted through the OUT pin. There are two indicators on the module board. A glow of green indicates that the power is on. The red LED lights up when an object is in the detection zone. Setting up the device is facilitated by the operation of the detection indicator. This allows the FC-51 to be configured to operate under real-world conditions. Setting the sensitivity of the sensor is performed using a trimmer resistor installed on the board. The obstacle is set at the required distance from the sensor photodevices. By turning the movable contact of the variable resistor on the board of the FC-51 module, the sensing distance is set, the red LED is turned on. Then the actuation distance is checked by moving the reflecting object.

— | HC-SR04 is an ultrasonic sensor that allows you to measure the distance to an obstacle in the range from 2 to 400 cm. It can be used as a presence sensor in a smart home or security system, as well as for various robotic systems. In addition, using this module, you can make parking sensors for a car. The module is a board on which an ultrasonic emitter, a receiver and a control electronic circuit are placed. The sensor has small dimensions and a simple interface: two power outputs (VCC and GND), an input (TRIG) and an output (ECHO) for data transfer between the controller and the module. The emitter transmits a short ultrasonic pulse, which is reflected from the object and received by the sensor. The distance is calculated from the time to echo and the speed of sound in air. The receiver receives the echo signal and outputs the distance, which is encoded by the duration of the electrical signal at the output of the sensor. The next pulse can only be emitted after the echo from the previous one has disappeared. This time is called the cycle period. The recommended period between pulses should be at least 50 ms. If a 10 µs pulse is applied to the TRIG signal pin, the ultrasonic module will emit eight bursts of ultrasonic signal at a frequency of 40 kHz and detect their echo. The measured distance to the object will be proportional to the width of the echo pulse.
