Hello guys, I need some help. I can’t understand why it's not printing out any value beside 0 on my serial monitor. So I use a Shunt resistor that has the resolution of 75mV for 50A. why the analog pin can't be read when connected to a resistor shunt? the data just reads 0 only... The real problem…

[image] rarrazn: I tried to check the analog pin readings Serial.println(analogRead(A3)); why is the result always 0? Is the result of analogRead(A3) always zero, or is the outcome of your calculation in post #1 already zero regardless of the reading of A3? It's not clear from your post. …

I tried to check the analog pin readings
Serial.println(analogRead(A3));
why the result always 0?
