Lesson Overview

The purpose of this lesson is to instruct students how to wire their Arduino combat robots. Students will learn to: 

• Identify the different electrical components of their bot

• Provide power to all their electrical components

• Wire the receiver to the Arduino

• Wire the Arduino to the motor driver and motors

• Upload code to Arduino to check for proper wiring

Required Kit Supplies

• 1x Arduino UNO

• 1x USB A-to-USB B cable

• 1x 9V to barrel jack connector

• 1x Barrel jack switch

• 1x AA battery pack

• 1x FlySky controller and receiver

• 1x L298N motor driver

• 2x Yellow DC motors

• 2x Motor wheels 

• 12x M-F wires

  • 2x Red - 15cm

  • 2x Black - 15cm

  • 8x Assorted - 10cm

• 1x Flathead screwdriver

• 9x Batteries - wait to handout until wiring has been checked

  • 8x AA batteries

  • 1x 9V batteries

Additional Required Supplies 

• Chromebook or laptop for each student

  • Arduino IDE installed or

  • Access to Arduino web editor with Arduino Create Agent installed

Keywords

• Motor Driver: an electrical device which controls motor speed and direction

• Receiver: an electrical device which connects with a controller to provide output signals

• Common ground: when multiple power sources are used in a circuit, a common ground must be used to ensure that all components are safely wired and properly receive data signals.
