Case 4 - Crash Detection with Crash Sensor

Case 4 - Crash Detection with Crash Sensor

 

Part 1   Objective

After you upload the program, the RGB LEDs on the RGB module connected to pin A13 on MegaPi are on when the crash sensor connected to pin A11 detects a crash and the RGB LEDs are off when the crash sensor does not detect a crash.

Part 2   Preparation

  • MegaPi x 1

  • RGB module x 1

  • Crash sensor x 1

  • 3-pin jumper x 2

  • USB cable x 1

  • Computer with network access x 1

Connect MegaPi to the computer by using the cable, connect the crash sensor and the RGB module to MegaPi respectively by using the jumpers, open mBlock 5 (PC client, web version, or mobile app), click +add, select mBot Mega from the Device Library, click Connect, and select the Upload mode.

Part 4   Practice

  1. Try to write a program by which the RGB LEDs are off when the crash sensor detects a crash and the RGB LEDs are on when the crash sensor does not detect a crash.

  2. When you turn on mBot Mega, the number of RGB LEDs lighting up equals the number of times the crash sensor detects a crash.
