Useless Box

A useless box is a wooden box with a lever on it. When you flick the lever it flips open a hatch on the top a arm comes out and pushes the lever back to close the lid.

Supplies

1x Motor with reducer

1x Battery (2x AA)

1x Toggle switch (SPDT)

1x Limit Switch

Hook up wire

Step 1: Design Circuit

First I designed my circuit online. So I have my circuit ready to copy onto the actual thing.

Step 2: Full Drawing Design

This is when I drew up a design of what I will be making.

Step 3: Soldering Motor Wires to Switch

In this step I soldered 2 wires to the middle pins of the switch.

Step 4: Attach Wires to Motor

Here I attached the wires from the switch to the motor

Step 5: Solderer 2 More Wires Together

I soldered 2 more wires together to use for the battery pack and limit switch.

Step 6: Attach White Wires to Switch

I attached the two connected white wires to the top right pin on the switch

Step 7: Add Battery Pack

Here I attached the white wires to the battery pack and the red wire from the battery pack to the switch.

Step 8: Add Red Wire

I added a red wire between the top left and bottom right pins on the switch.

Step 9: Attach Limit Switch

I finished the wiring by attaching the limit switch to the last pin and the white wire. This completed the wiring.

Step 10: 3D Design of Arm

Here I designed my arm on tinker cad that I will use.

Step 11: Make Box

I forgot to take a photo in class so I uploaded one from google. In this step I sticky-tapped and glued the floor and walls together of the box. I ran out of time to add a roof.

Step 12: Braket

Again I have no picture of this step but I attached the motor and limit switch to a 3D printed bracket and then screwed it to the floor of the box. This was my finished product because I ran out of time to add the roof, like I mentioned earlier. I also never had my arm printed so I am missing that.
