A practical generator. In this diagram the iron core that fills the space between the axle and the rotating coils has been removed for clarity. The magnetic field is provided by the two electromagnet coils ('field windings') which also have iron cores.
is a Scratch modification that allows for simple programming of the Arduino open source hardware platform. It provides new blocks for managing sensors and actuators connected to Arduino. There is also a sensors report board similar to the PicoBoard on
