Im using a BC547 on the output of the 555 timer to increase voltage levels. Basically the 555 output turning on the Transistor. Emitter is to +9, Collector is to the load, other side of load to ground, and 100 Ohm resistor from 555 output to transistor Base.
The amount of current from the Base of the transistor is what causes the transistor to heat up and this is a problem for me. Is a relay better in terms of lower heat dissipation? What is an alternative as I don't want heat dissipation at all.
