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.

  • \$\begingroup\$ thanks but could you please explain better what i should do? i don't know electronics very good because i just started to "play" with it, maybe a circuit scheme would be helpful \$\endgroup\$ Jun 10, 2020 at 21:21
  • \$\begingroup\$ @Er pupis down .Get say a 1n4148 diode and connect across B.E. of your transister with the black line on the B. \$\endgroup\$
