uLisp® is a version of the Lisp programming language specifically designed to run on microcontrollers with a limited amount of RAM. It currently supports the Arduino ATmega-based boards, Arduino ARM SAM/SAMD-based boards, Adafruit ARM SAMD51-based boards, BBC Micro Bit, and MSP430-based LaunchPad boards. You can use exactly the same uLisp program, irrespective of the platform.
Lisp is a flexible language, with many advanced features that make it easier to program in than C or C++, so it’s ideal for learning about fundamental programming concepts. It’s also an ideal language for expressing complex ideas, such as teaching a robot to solve mazes or finding the shortest route on a map.
Version 2.4 supports Adafruit’s M4 boards
The ARM version of uLisp now includes support for Adafruit’s M4 ATSAMD51-based series of boards: the Adafruit Metro M4, Adafruit ItsyBitsy M4, and Adafruit Feather M4. With 120MHz processors these are now the fastest platforms for running uLisp. For more information see Adafruit M4 Boards.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
