Arduino + Processing: Make a Radar Screen [2 part tutorial]
In this 2 part tutorial [Lucky Larry] develops a nice Arduino to Processing App to visualise distance data in a “radar” way.
Part 1 (Circuit & Arduino) and Part 2 (codes and Processing).
He is using a SRF05 Ultrasonic range finder and a servo. He managed to adapt this tutorial to the more common Sharp Infrared Rangefinder.
Shopping list
SRF05 Ultrasonic range finder
Arduino Deumilanove w/ ATMEGA328
Breadboard / Prototyping board
Jumper/ Connector wires
1x Servo (has to need no more than 5v supply)
Here’s a video below of it all working! There is an issue to bare in mind with the SRF-05 and thats that it works best as a static range finder, it emits a conical wave which will bounce back off of anything small or large and has a wide detection field of vision so it may pick up something that’s not directly in front of it. As you can see by the below image the detection range is so wide that it doesn’t truly see all the gaps as its detected something else in its field of vision.
