The idea is that the Pi (via Python) will send messages to the PC broker to tell the ESP8266's LED what to do. -Microcontroller: AVR series (Atmega, Arduino), Stepper motor controller, AC&DC motor controller, Communications (RS232, RS485, CAN, I2C and SPI),. The SN65HVD72 IC converts the 3. sudo python /home/pi/watermeter. RS485 CAN HAT for Raspberry Pi, Allows Stable Long-distance Communication Overview. need a walkie talkie with simple electronics used. DFRobot I2C ADS1115 16-bit ADC module can accurately collect and convert analog signals. We will send ‘Hi’ from the Arduino to the Raspberry Pi every 2 seconds. Then the company created their ModBerry industrial computer, which then had RS-485 and RS-232 serial ports, a number of interfaces, digital and analog inputs and outputs. To establish wireless communication I used XBee Pro Series 2 from Digi International.
