Add Obstacle Detecting Whiskers to Your Robot

Step 4 Wiring

Time to wire everything up. To do this download the wiring diagram (05-(WHIS)-Wiring Diagram.pdf). and follow the steps.

What's Happening

• Essentially we have added two switches to the front of our robot. The pickups on the two WHIS-02's run to the Arduino (we will make these high by default in our code). When your robot bumps into something the whisker which is connected to ground, presses against these pickups and pulls your Arduino pin low.

On to the programming.
