Relay control 105 not using transistor with dual LED indicators

01:46:45

Early learning circuit to control a relay with a transistor (using pull down resistors on base) with LED indicators on low voltage side.  It actually  works !!!!!!

I guess, you forgot the "must operate" which you set to 1mV. Std 5V relais do need around 3+V to operate and release much lower maybe at 0.5V The default values in everycircuit are for a 5V relais. Have fun!
