Lesson 5

Tembusu Integration Board

It is used to connect the Groove modules to the micro:bit.

Groove modules

• Grove Buzzer: Connects to digital output, emits tone with output is high
• Grove Sound Sensor : Connects to analog output. Based on the LM358 amplifier and electret microphone. Used to detect sound strength of the environment.
• Grove Rotary Angle Sensor: Produces analog output between 0 and VCC. The angular range is 300 degrees with linear change in value.
• Mini Fan (DC motor) : Connects output to a DC motor. Turn on when pin is turned to high.
• Grove LEDs: Display light effects from digital outputs.
• Grove Moisture Sensor : Detects moisture level based on resistivity
• Grove Mini Servo Motor: Output motion control device where its position can be precisely controlled
• Vibration Motor: Connects to a digital output. When triggered high, it produces vibration effect.
• Light Sensors : Detects level of ambient illumination to trigger light brightness.
• Grove cables: Easy to use plug-and-play connectors in various length

Task 1

• Program the LED to display the angle when your micro:bit is tilted up and down.
• When the angle is more than 10 degrees, the buzzer will emit a sound.

Task 2

• Program the LED to display the bearings of the compass direction.
• When it is pointing to the North, the buzzer will emit a sound.
