Goal - To be able to turn on and off using single battery
I made alteration as shown - purple and green. The circuit is flickering. Is it possible to make this circuit work, with any changes.
Why 1 battery? because I use a 12V car battery, and no AC power.
Could it be the code on the ESP? And how much amperage is the load drawing? Power = Voltage x Amperage -> 120watts / 12 volts = 10 Amps. This is the maximum power u can use off the battery
