The model Cash machine is built from the Lego Wedo 2.0 educational kit. The model uses a spur gear to increase the speed of the rollers that grip the bill. A distance sensor is installed in the area where the bills fall – as soon as the sensor reacts to the accepted bill, the total amount increases (the counting algorithm is implemented using a variable).
The set includes step-by-step building instructions and an example of program (in Lego Wedo 2.0 environment).
ATTENTION! Additional material is required – paper tape, scissors.
