Post a close-up photo of your circuit and a hand drawn (or better) schematic of the circuit. Also include the value of the resistors you used.I have a simple circuit with 2 transistors making an and gate and switches to turn on the transistors and a led to light up when the 2 switches are on, but
it doesnt work the transistors just heat up.
ps.sorry if i`m noob
Your transistors have been damaged because you should have a resistor between the (+) and base of the transistor. Look at the datasheet for the transistor and look up the max current into the base.
I think he is experimenting - making an AND logic gate.Don't even need the transistors just put the 2 switches in series.. (or are the switches momentary..even so)
