List of things used in the hyperbody Workshop project
1. 6 servo motors 2. 1 ultrasonic sensor 3. 1 loudness senor 4. 1 Arduino/Genuino Uno 5. 1 Arduino Mega 6. 2 external Arduino power supply 7. 1 breadboard 8. 2 3mm wooden board 9. 1 half-translucent plastic sheet 10. 1 ring of 25 Neo pixel LED lights 11. 2 USB line 12. A bunch of wires
Code Sample
The code works by mapping the ultrasonic distance sensor data into the servo motor. So that the shorter the distance the sensor detected, the larger angle the servo motor turns and the flower will open. When the distance recorded is long, the servo motor will turn back to smaller angle and the flower will close.
