copper wire following robot: building a dual Hbridge to drive a robot. but my transistor TIP 42 and TIP 120 overheat Answered
i have a dual hbridge but its overheating im a beginner in electronics and i dont know how to fix this i have attach a schematics of my circuit...i used 4 npn transistor (TIP120) 2 to control the Hbridge and 2 others that form the hbridge , 2 pnp transistors (TIP42G) , (4) 1Megaohms resistors. TIP transistors are able to take up to 150 degrees...i heard of heat sink and voltage follower to help with the overheat . but i cant make it work. is my circuit correct..if yes how can i get rid of the heat?
