Hi there! I am facing a weird issue with my circuit currently, where even though the inbuilt ESP-32s LED lights up, the ESP does not work the components connected to it. More explanation on this is described as follows: The cytron mdd3a driver that I am using is a buck convertor type driver...

Hi, I have created a 3 chip instrumentation amplifier using an LM324 Op-Amp for a project. I have simulated the circuit in Circuit Lab using a differential DC input voltage of 3.5mV. The gain is approx. 982 and I have split this up providing roughly 18 in the amplifier and 54 in the first...
