Cost Breakdown (est 2022)
| Component | Cost | Example Source |
|---|---|---|
| Arduino Uno | $12 | Example on Amazon |
| Bluetooth Module | $4 | Example HC-05 Module on Aliexpress |
| Breadboard | $6 | Solarbotics |
| DC Motors with Wheels | $4 wheels + $7.50*4 motors = $34 (Solarbotics) or different solution $10 (AliExpress) | Solarbotics AliExpress |
| Motor Controller | $11 | SparkFun Dual Motor Driver TB6612FNG at Solarbotics |
| Batteries | $30 for 2 (35C 1100 mAh Lipo Batteries). Could use other more inexpensive battery options as well. | |
| TOTAL | ~ $50 to 100 |
Note that the above costing does not include:
- Wires
- Robot Physical body. In the example shown it is a short piece of wood, plastic sheets, and some foam border.
- Screws or nails
- IF using LiPo batteries, you will also need an appropriate charger for LiPo batteries.
- Note that a half-size breadboard is sufficient (full size is shown).
Note that if you choose to LiPo batteries, learn how to properly care for them. I also do not allow students to develop circuits powered by LiPo batteries. They must first use a USB wired connection and then when ready I will hook up the batteries for them (do not want an accidental short circuit!).
