Radar Gun With Gyroscope.

This is a speed measuring device that can calculate speed using both a linear measurement and a angular measurement.
Supplies
The material you will need include:
- 1 Arduino Nano
- 1 Ultrasonic Sensor
- 1 Small breadboard
- 1 Serial LCD (Or any display of your choice you will just have to make a slight modification to the code)
- 1 Gyroscope (I used a )
- 3D printer with filament to make the casing (optional)
Code and the .stl for the case: https://github.com/John-Alimoglu/SpeedCameraCode

Attach your Arduino Nano to the front of the small breadboard. Then glue the breadboard down so the USB port is accessible through the hole.

If required solder the pins onto your gryoscope. Make sure you use the straight pins not the 90 degree bent ones.

Install your Gyroscope next to your Arduino

Wire up the power pins on the gyroscope. Then wire SCL to A5 and SDA to A4. This allows us to receive info from the gyro.

Solder 4 wires on to your ultrasonic sensor then wire the ground one to ground, vcc to 5v, trig to pin 2 and echo to pin 3.

Push the ultrasonic sensor into its slot.

Wires the displays power pins then wire the RX pin to the Arduino Nanos TX pin

Use some wire, string or whatever you like to attach the screen to the box.

Add your switch into the slot in the lid and wire it to pin 4 and 5v.

Simply add the lid and run the code.
