i have connected microcontroller to two relays via ULN 2003 (relay and led driver ic) . I am using sensors to select the relay operation with time delays.
My software works excelently and the
relays operate as directed by software without fail.
But the problem starts when i load the relays with small servomotors operating on AC mains , the software hangs and goes bersek and ihave to reset the controler.
Now if i replace the motors with ac lamps again the program works fine for hours of testing.
How does the inductive load of motors effect the working of software when the motors are isolated from dc supply as i am using relays ???? and can any one suggest what should i do
