How to Wire a Pressure Sensor to Arduino
- First, see how to program a button - [1]
- Connecting a button involves connecting one wire to 5V from one of the Arduino pins, and connecting the other wire to the Arduino pin that does the reading. We also need a resistor to ground - so that when the putton is not presssed, the pin is pulled down to 0.
- Read about pin function as input or output on Arduino - [2]
- We can avoid external resistors because Arduino contains pullup resistors that can be activated in software
Summary: Save yourself the complexity of extra parts by avoiding extra resistors, because you can use ones that are inside the Arduino already. See Instructables - [3]
Pressure Trigger Switch
- For the OSE CEB press, we use a switch that is simply an on-off function
- This can be read as in the above example.
