Hello all
Ive recently been working on a solar panel sun tracker circuit, found on this website **broken link removed**
The problem i need a hand fixing is i believe that my motor (in my case a car wiper motor) is producing back EMF, as it turns on/off my relay makes weird sounds aswell as little sparks can be seen on the inside contacts. If i continue running the circuit like this one 555 timer blows.
The circuit runs fine off a smaller hobby motor.
cheers for the help
