1. Parts preassembly
Some of the parts need preassembly to be ready for the final assembly stage. In this section, we will combine electronics and 3D printed parts. Before you start, be sure you have the correct electronic part and the correct 3D printed parts. In every folder of the parts with the preassembly stage, you can find photos of the electronic part you need also the code of part can be founded in the README file of the 3D printed parts folder.
This is the only stage we will need the following tools:
- Side cutter
- Soldering iron
- A small Philips screwdriver
- A flat screwdriver
- Hot glue gun
- Superglue
Remove a small piece of plastic from the yellow motor using the side cutter.
Prepare two wires of different colors, take the side cutter and cut the one of two female to female jumper wires, after carefully remove a small length of the plastic isolation and expose the copper inside the wire.
Solder to the two motor terminals the wires.
Insert the motor inside the bottom part and pass the wires through the little slot of the top part.
Press the bottom part against the top part until secure.
Connect three female to female jumper wires to the sensor and write down the wire color to pin connection e.x. "RED -> 5V , BLACK -> Ground, GREEN -> Signal".
Slide the sensor inside the bottom of the 3D printed part in the special slots.
Slide the sensor disk on the shaft and place it in the special slots inside the bottom part.
Pass the wires through the little slot of the bottom part.
Press the bottom part against the top part until secure.
Connect three female to female jumper wires to the sensor and write down the wire color to pin connection e.x. "RED -> 5V , BLACK -> Ground, GREEN -> Signal".
Slide the sensor inside the bottom of the 3D printed part in the special slots.
Slide the sensor disk on the shaft and place it in the special slots inside the bottom part.
Connect the shaft coupler to the shaft. Later you can connect the odometer with the motor shaft using the coupler.
Connect three female to female jumper wires to the sensor and write down the wire color to pin connection e.x. "RED -> 5V , BLACK -> Ground, GREEN -> Signal/Digital".
Slide the sensor inside the bottom of the 3D printed part and gently pass the two Led through the holes. The blue part of the sensor should be the upside.
Pass the wires through the hole of the top part.
Press the bottom part against the top part until secure.
