Hi guys
I am trying to work out how to do the following
Sender ESP32 using hall effect sensor UGN3503UA and a magnet connected using ESP NOW
Receiver ESP32 output 0 - 3.3V
I have got the above part working but am stuck on how to do the next part
How can I make a circuit that uses the 10V external power to go from 0 - 10V using the output voltage of 0 - 3.3V from ESP 32
The analog input works with a 47K potentiometer as a voltage divider using 10V to make it 0V to 10V
So I want to use the 0 - 3.3V to convert the 10V input like the voltage divider with 47K pot but instead, use the ESP 32 kind of like a digital pot?
Any help would be much appreciated.
Looks like I could use a digital pot to do this but any other ideas would be great
