So I built a pt4115 circuit to control my LEDs! it has a 0.12Ohm resistor so it should give me 0.860~ma of current!
but the weird thing is that as I turn the votlage fro 0 to 30v on my power supply it goes up to 850 then drops down to 30 and goes up to around 850 and again jumps down but when it goes to 30v it's around 1.2A! it keeps changing if I change the voltage!
I attached the pictures!
