Lesson Overview
- In this activity, students will make a smartphone gesture-controlled robot whose motion will be controlled when you tilt the smartphone.
- If the smartphone is tilted forward – the robot will move forward.
- If the smartphone is tilted backward- the robot will move backward.
- If the smartphone is tilted left – the robot will turn left.
- If the smartphone is tilted right – the robot will turn right.
- If the smartphone is flat or parallel to the ground – the robot should be at rest.
- During the activity, students will go through the following activities:
- Circuitry and testing the circuit.
- Programming of the robot.
- Reading sensor values and printing it on TFT display.
