Take a gander at the Giant LED bar graph which [Chunky Hampton] recently ... but in this case it’s an Arduino. [Chunky] uses the meter to display power output from his stationary bicycle generator.

The use of this book as a jumping off point could have used a little help. For example, the LED bar graph uses 10 pins on the Arduino, which is great for an introductory example.

The bar graphs in particular look fantastic, with silky-smooth animations. Posted in LED Hacks Tagged 16x2 , animation , arduino , display , oled , rom , US2066 Post navigation ...
