i made this project but it is not working and the transistor is heating up very fast, i couldn't find anything regarding this specific project but as far as i understood i should maybe use another transistor, what do you suggest?
Q1 will blow up. Veb, the reverse breakdown voltage between the base and emitter will be exceeded. Place a reverse diode or a LED across base-emitter. Remember that most silicon BJTs can only handle 6 to 8 volts reverse across base-emitter.
