While this garage stop light does require some technological and electrical finessing, it's easy to follow along! You certainly don't need an Engineering degree.

Step 1

• LEDs (red and green)
• Resistors
• Arduino Uno
• Breadboard Jumper Wires
• Ultrasonic Sensor
• Electrical Tape
• Battery Pack
• USB type A to USB type B cable (printer cable typically)
• Box (storage device)
• Soldering iron
• Wire cutters

Step 2

Take to resistors, shorten the ends but cutting them. Connect two wires to the end. Wrap in electrical tape.

Step 3

Trim two LED ’ s (one red one green) to fit into the wire harness. The longer side is the positive side.

Step 4

This is called a bus, which is how to connect multiple wires to the same place. I have soldered all the negative wires from the ultrasonic sensor and LED ’ s. There should be 4 wires connected. Wrap this in electrical tape.

Step 5

Notice the color of each wire to determine where the other end should be connected.

Step 6

Connect the ultrasonic sensor and LEDs to the digital output side. I was using red wire for power, so to denote the red LED I used yellow wire. The green wire is from the green LED. The white and orange wires are coming from the ultrasonic sensor.

Step 7

The ground wire is coming from the connected grouping and the power wire is coming from the ultrasonic sensor.

Step 8

Use the USB cable to plug into the computer.

Step 9

Go to the Arduino website and download the software for the Arduino for your OS.

https://www.arduino.cc/en/Main/Software

Step 10

Copy and paste the text from github.com/ (this will be something soon) into the Arduino window.

Step 11

Click the upload button.

Step 12

Place all of your components into your storage device. I traced out holes for the sensor and the LEDs. Plug the battery into the Arduino.
