Arduino Radar Gun
Introduction
This is a long term project, so this page will be updated as the project continues. The goal here was to take control of an off-the-shelf radar gun. The gun used for the project was a "Bushnell Velocity Speed Gun" and was purchased on Amazon. An Arduino Leonardo is being used due to it having x12 Analog Inputs. Since the Leonardo is based on the ATMEGA32U4, any of the "Arduino Clones" would work, like this one
Phase 1 - Reading the Speed Data
Video will be coming soon...
Connections
All x12 Analog Inputs are connected to the Numeric LCD pins on the gun. A0-A5 are the standard hookups to the Arduino, but A6-A10 go to: 4, 6, 8, 9, 10 Note that the ground connection is made where the battery clip wire terminates into the board
The trigger board cable brings up the positive 3V terminal from the battery stack, which is where I connected my 3.3V source wire. You can see that the two pins on the left are bridged together, which made the soldering much easier
