help with shorting probem on my curcuit Answered
This circuit does not work because of a problem with power shorting to ground at the motor. I think that is the only problem. The servo provides a 4.5v power source and the polarity can switch allowing the original 4.5v servo motor to run forward and reverse. I am making this to run a motor on 12v and the servo on 4.5v. R1 keeps the transistor saturated and the R2 is in there because I read it would help the transistor turn off completely. I made this circuit work (the right voltages went to the right places) in one direction but now it is more complex, I think Iâm having a shorting problems. Can anyone help?
