Tiny Lisp Computer
This article describes a self-contained computer with its own display and keyboard interface, based on an ATmega328, that you can program in Lisp. You can use it to run programs that interface to components such as LEDs and push-buttons via the I/O pins, read the analogue inputs, and operate external devices via the…
