Step 12Mount the Wheel assembly to the Solar Cell
We are now ready to attach the wheel frame to the solar cell. You can do this with glue, but solder is much better!
I will solder my frame to the fat metal strip on the back of the PCB, but it is covered by a green coating. Scratch the surface of the PCB (like in the picture) to create an exposed patch where you can solder on a breadboard wire.
If you want, epoxy your wire here instead. DON'T USE HOT GLUE! Hot glue will get soft and melt in the warm insides of the clear ball, especially in sunlight!
