Im using 2x555ics not 556. All caps are ceramic 103,104 and 224k
Problem is with second 555ic circuitry cos first one is generating 50hz picture attached.
10k pot one side 1900-2000us returned from pulsein(), fully turned to opposite side veryhigh values didnt even noted them.
Didnt change values for capacitor and resistor because of calculations by that guy are right it “must” produce 1ms duty cycle when fully off.
