Hi...
I designed a circuit for control AC Bulb throgh bluetooth. but the problem is, when the rellay turned on with load, Device is restarting(microccontroller reseting).
in my design, i already connected diode across relay coil and also 104 capacitor is connected across microcontroller Vcc & Gnd pin.
There is no problem when no load is connected to relay. and also try with 0.5W LED bulb, and the device works perfectly. But when i connect a 9W bulb, the controller reset when relay turned on.
i check internet about this problem and everyone says add diode across relay coil. but, its already added in my design.
please help me to rectify my problem.
NB: iam using 24 V relay. and supply it with 24 V power supply. then convert it with regulator and provide 5v to controller.
Thank you
