CardBoard Microcontroller

The CardBoard Microcontroller can control one or two servomotors. A potentiometer or light sensor can be used to move 180-degree servos to a specific angular position, or change the speed and rotational direction of continuous servos. The board can also run servo(s) automatically, with direction, speed and range written into the Arduino program. Making use of the ATtiny85, the CardBoard is designed to be inexpensive and simple enough to use in classrooms and out-of-school programs, yet robust enough to travel and display with interactive PaperMech projects. This design requires some basic soldering, which can be done by learners or by educators beforehand. Learn how to build one yourself using the resources and video below.

Arduino sketches for CardBoard Microcontroller

Arduino sketches can be modified to control how far and fast a servo moves, or how it responds to inputs like a potentiometer (dial) or photoresistor (light sensor).
