Three approaches to control it will be considered here: - via Raspberry Pi; - via Micro:Bit -via Crumble controller 1. Raspberry Pi based In this Raspberry Pi based Junkbot design a combination of Python and Pimoroni's Explorer HAT PRO are used to control it. Explorer HAT Pro is a good choice, it can control two motors with a library provided to simplify the programming. For this the Junkbot was the one shown above: a drinks can, pen, LEGO bits, motor and broken propellor. Before the Explorer HAT can be used the library needs to be installed via the Terminal and the instructions below curl get.pimoroni.com/explorerhat | bash Python code to control the junkbot is shown below. import explorerhat from time import sleep def spin1(duration): explorerhat.motor.one.forward(100) sleep(duration) explorerhat.motor.one.stop() def spin2(duration): ...
This is an initiative to mix sustainability, engineering and computing to students.
