  • Based on your environment and technical requirements, choose the best device to complete your project. Make sure you device is transmitting data through RS485. Our project calls for a Arduino UNO using a RS485 shield with an humidity sensor to transmit...
  • Step 4: Code

  • Here I will read the analog port and look for a high signal. And switch the pins accordingly. I have written everything in comments and code is self-explanatory. Whenever it reads a certain voltage at analog pin it activates the switch. This switch can...

  • Analog to Digital Converter (ADC)

  • Embedded computing is basically computing integrated to the real world, and the real world is pretty much analog. By default, electrically measuring analog real world values produces analog voltage or current (which can be converted to voltage using...
