Measure distance and view it on demand using a ProTrinket, an Ultrasonic ranging module and an LCD screen.
Replaced potenciometer with 2 resistors and added button to turn on LCD backlight!
Find Ultrasonic Trinket with LCD display and on off button code here!
Rebuilt the project using one breadboard. We also added a button which turns on the sensor and the LCD only when pressed.

We built a first version of our project using a Pro-Trinket 5V plugged into FTDI and USB.
We found a better sensor, which is not InfraRed, but it's ultrasonic with a bigger range.
We're now gathering the things we're going to need.
