Sending data over Laser from one Arduino to another using a keypad and an LCD(100b/second)

I want to make a watch which has led, so instead of a simple watch I came with a unique idea. This watch shows time in binary digits.

This project connects the ADLX345 3-Axis accelerometer to display a location on an 8x8 LED matrix using the MAX7219 LED driver chip.

Wake to any of 100's of MP3 messages from SDRAM. Scrolling display w/remote shows clearly w/o glasses. Temp too!

An Arduino based self-setting clock which can display temperature and other data from Homematic systems.

Ever wanted to display any hand-drawn image on your fancy oscilloscope? Well, now you can!
