Hello,
I want to learn how to use an arduino/esp8266. As my first project I want to measure the voltage and the current.
I thought I use a display to show the values and I want to switch a LED on if a defined amount of watts is reached.
Is there a way how I can measure both values. The NodeMCU has only one ADC (A0) input. I also read, that the ESP8266 has problems if the A0 input and the Wifi is used at the same time.
Any advices for me?
Thanks in advance,
Chris
