Pushbutton Switch
The pushbutton could also be called a touch sensor. Pressing the red
button actuates a switch mechanically allowing electricity to flow from
contact 1 (middle contact) to contact 3. At the same time the circuit
between contacts 1 and 2 is interrupted. So you can use the pushbutton
in two different ways:
A
s a "Normally open switch" (NO or push-to-make switch)
contacts 1 and 3 are connected.
Pushbutton is pressed:
Electricity flows
When the pushbutton is not pressed:
Electricity does not flow
As a "normally closed switch" (NC or push-to-break switch)
contacts 1 and 2 are connected.
Pushbutton switch pressed:
No electricity flows.
When the pushbutton is not pressed:
Electricity flows.
Trail Sensor
The infrared trail sensor is a digital sensor for identification of a black
trail on a white background at a distance of 5 to 30 mm. It consists of
two transmitter and receiver elements. For connection you need a digital
input on the ROBOTICS module and the 9 Volt power supply (positive
and negative poles) on the battery tray.
