is the last one with code tags? No? what is it , and what to do

25

Yes, you have the code tags correct. Unlike Golam’s which did not include the first few lines.

26

Hi, @wimtttt

Can you please post a copy of your circuit, a picture of a hand drawn circuit in jpg, png?
Hand drawn and photographed is perfectly acceptable.
Please include ALL hardware, power supplies, component names and pin labels.

Please provide links to data of powersupplies and other hardware.
Thanks.. Tom.... :smiley: :+1: :coffee: :australia:

I have missed only the following line which is added now:
#include <Wire.h>

29

Than you Golam Mostafa, I include it, was this code important, do not know, was already working. Only thing I want is: the amp potmeter does 2 things. change amps till 100 %, and change pulsation til 50 %, is ok, but the last one better on my not used potmeter, 4 till 100%, if possible. And that is the code in the first code Gemini says, but the code is much shorter, tried it, and actually it does nothing, so forget the first script
