Air Mouse: Construction and Working
Here is the circuit:
Conversation with a friend on Air Mouse Working Principles:
Subbu: Manav… the air pigeon… how is the mouse like movement achieved?
Manav: Dark magic, with evil-looking sacrificial knives on scantily clad virgins under pale moonlight! LOL! just kiddin 😉
- It actually uses an (analog) accelerometer that responds to the Horizontal (X) and Vertical (Y) tilts of the device in terms of voltages.
- Then the microcontroller ATMEGA32 sends the tilt data via the serial-port to the PC after converting it to digital using an ADC.
- This is where the Visual Basic Driver takes over and sends mouse move events using user32.dll to Windows .
- For the Clicks, there is a push button on the PCB for user-inputs.
