After the self driving car games we now get to make flashlights! Making the flashlights requires lots of materials. Some examples are the light, the wires, switches, and many more. This unit combines all that we’ve learned, the soldering iron, light switches and so on. To connect the materials you use solder. Before you can even start soldering you need a plan. There are a few basic rules you need to follow. The flashlight needs to fit in a certain box, the flashlight also needs to be waterproof. When you’ve made the plan you need Mr. Calvert’s approval. Even after planning your still not done! The next step requires you to list the materials you need and the exact lengths. Finally after that is done you need Mr. Calvert’s approval again. After he says yes you can start your soldering!
