[Lars] shows you how to get a perfect score on the first four levels of BIT.TRIP RUNNER by using an Arduino to time and send button presses. This is a pretty simple game that uses a couple of ...

The other three buttons set the logic level, shift it into the chip using the clock signal, and push the stored values to the outputs using the latch.

Running out of GPIO pins? Learn how to connect multiple buttons to just one Arduino pin using clever wiring and resistor techniques. Perfect for compact projects, keyboards, or when using small ...

Use a quadrature encoder and a display, with some sort of acceleration function on the motion so that it can set the full range of numbers in a reasonable time Use a quadrature encoder and a display, ...
