This section introduces you to Roamer’s control features. It explains how you program inputs to work with sensors.
The doorbell is a simple control gadget: when you press the button, the doorbell rings.
In control thinking the doorbell responds to inputs (pressing the button) by producing an output (ringing a bell). You can also think the doorbell senses you pushing the button and respodds by rining the bell.
Your Roamer robot comes with an input port for sensors and an output port for gadgets. The triangular marks remind you which is which.
You will learn how to program Roamer output instruction.
