I build a switching circuit.Here NPN transistor base gets switching signal from microcontroller & collector connected 9volt 6f22 battery through small resistor Emitter grounded directly. here 9volt sugar cube relay used & relay output (N/o)given to transmitter circuit.
Here battery gets drained within 24 hours without sending any switching signal from microcontroller.here just circuit ON condition only.
Plese help me.
Pl.looking forward valuable replies with great thanks.
