Motion2USB

I utilized an HC-SR501 motion detection module in conjunction with a Digistumb attiny85 based Arduino board to activate my computer. The Arduino boasts a straightforward program that sends a capslock keystroke when motion is detected. Edit: I have revised the arduino sketch to function more effectively alongside my touchscreen onscreen keyboard. The case doesn't fit perfectly, and the digispark board wouldn't fit without modification, so I employed a dremel tool to make it work. Feel free to create a better case if you can improve upon this design. Edit 2: I've adjusted the design to accommodate the boards more accurately, but this iteration hasn't been tested yet. If you print and utilize the V2 design, please leave a comment with your feedback.
