Step 6Construct the Control Circuit
iImage Information

The control circuit is very simple for this device, the number of diodes that are shown may need to be adjusted. The output from the Drive LED output didnt go to zero so the diodes are there to drop some of the excess voltage so that the circuit does not turn on until the drive output actually turns on. The 1000 uF cap is there to smooth the flashing drive LED output. Without the cap the circuit would still work but the LEDs and the motor would be pulsed. I tested the circuit concept on a breadboard first to make sure it worked before making a permanent perf board version. The component locations were made to be very compact since there is limited room in the case (if you want everything to remain hidden).
