7400 competition entry: Bad driver feedback display

in 7400 contest by DP | 1 comment

Gagandeep built a “bad driver” feedback display. It’s a huge 40X16 LED matrix spanning ~80cm in width, and it’s designed to be placed on the rear windshield of a car. The spacing of 2cm between LEDs is enough to ensure that the driver doesn’t have an obstructed rear view.

Using 2 74HC595 8bit serial in parallel out converters to control the 16 rows, and 5 of the same to control columns he built up his LED matrix. The logic chips are driven by a AT89C51 MCU. Check out the video of this project here.
