Overview and Wiring

Ultrasonic sensors are excellent at proximity detection. Whether on a robot or protecting an area. The Adafruit shop carries an excellent selection of sensors by Maxbotix.

The LCD display with an I2C backpack works well in Trinket projects as an informational display. It only requires two of the five Trinket pins.

Sensor monitoring is very common for Internet of Things (IoT) projects. This project can be placed in a very small enclosure and used anywhere sensing is needed. The code and concepts may be used in a number of your own projects.

Software Libraries Used

To maximize the functionality of software on Trinket, new libraries need to be installed. See the All About Arduino Libraries tutorial for details on how to download and install these libraries.
