Arduino Code
Arduino Code will be uploaded soon.
Pattern Generation
To create an image/patterm, you can use the POV image maker application.
Uploading the Pattern
- Install USBasp driver on your computer. Note that the it will show up as not recognized if the reset sequence is not followed
Reset Sequence for uploading new pattern/image
- Perform reset sequence every time you connect the kit to the computer.
- To upload a new image, hold down the BOOT button, press and release the RESET button and then release the BOOT button as shown below.
- Note the LEDS will stop blinking once the kit is detected by the computer.
