You'll need to bend the sensor transistor so its face is facing where the magnet will be located. Move the sensor up to the motor mount, mark its location, and then determine which side of the magnet makes the LED light when brought near. Mark that...

A custom-made relay switched circuit board uses NPN transistors. I could have bought a pre-made 4-channel relay board, but I wanted to make mine from scratch. This DIY project lets me remotely control household electronics from any web-enabled...
