Chapter 6, Building Robot Basics - Wheels, Power, and Wiring

• Why is it a good idea when using multiple Raspberry Pi "hats" or bonnets to look at their pin use?
  • Hats may use the same I/O pins for different purposes, making them incompatible.
• Why have we chosen to power the Pi separately from the motors?
  • To avoid brown outs, resets caused by noise or voltage drops from the motors
• What are the consequences of too small a motor controller?
  • It will overheat, causing it damage or to shut down.
• Why do I recommend test fitting before buying any parts?
  • To ensure the parts will fit together on the chosen chassis
