Step 1: Parts and the Circuit
- 1x Arduino leonardo (pro micro)
- 2x HC-SR04 Ultrasonic sensor
Check the image for the connecting.
Arduino code is on the bottom.
The idea is very simple:
If swipe right, then the left sensor detect first, and store "1" value in the arduino eeprom.
When hand reach the right sensor, the code check the eeprom for value.
If the value is "1", the app know, the gesture coming from the left, and the leonardo
send to the windows "right arrow key", and clear the eeprom.
If we swipe left, the right sensor detect first, and store "2" value in the eeprom.
When hand reach the left sensor, the code check thee eeprom again for value.
If the value is "2", the app know, we started the swipeing from the right, the leonardo
send "left arrow key", and clear the eeprom, ready to next measuring.
