BlinkM RGB LED Controller2011-05-01
The PC reads the joystick position and communicates messages to a Parallax Propellor microcontroller . The microcontroller processes the messages and then controls the BlinkM RGB LED using its I2C interface.
This is a simple project for controlling a BlinkM RGB LED with joystick. The joystick is attached to a PC, which communicates the inputs to a Microcontroller with the BlinkM LED attached. This project is way over engineered for simply controlling an RGB LED. I’m using it as an early test for a larger architecture I’ve been working on for more advanced robotic control.
The joystick is a little different than most because it has two slider controls. I have the controls setup as follows:
- Left Slider: RED component
- Right Slider: GREEN component
- Stick Y-Axis: BLUE component
- Trigger Button: Decreases BLUE component by one-half
I did the video mainly to experiment shooting video in the dark.
