Robot trapeze with CRICKIT @adafruit #adafruit #CRICKIT #robots


This is a robot trapeze with CRICKIT. The accelerometer detects the best time to let the robot go. Learn, code, and video.

Crickit – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express that lets you #MakeRobotFriend using CircuitPython, MakeCode, Arduino, etc.. robotics, arts, crafts, audio animatronics, sensors, agriculture/robot farming, physical computing, kinetic sculptures, science experiments, telescope control…

The Crickit is powered by seesaw, an I2C-to-whatever bridge firmware. So you only need to use two data pins to control the huge number of inputs and outputs on the Crickit. All those timers, PWMs, sensors are offloaded to the co-processor.
