Lab 43. Dashboard: analog input
Expected completion time of this lab:
.
The analog input pins only support a voltage between 0 and 1.8V. NEVER apply a volyage outside that range, or you will fry the board.
Test the voltage of your input using a voltmeter before applying to the board.
For testing, you can leave the pin floating (the input voltage should be around 1V), or tied to ground.
Create the following Node-RED flow to enable analog input pin A0
You should end up with the following dashboard
Extra points!
Create little control loops between sensors and actuators!
