“Have need your own mini-radar system? Then why not consider making one of your very own!
In this short tutorial, we’ll take you, step by step,(more or less) through the process.
Like any project of this nature, you are going to need a few bits and bobs. For this build, you will need:
HC-SR04 ultrasonic sensor
SG90 servo motor
1.8” ST7735 Display (or equivalent)
9V battery and connector
Electrical wires and soldering gear.
Assorted PCB wire female connectors and male pins.
A 3D printer, or ask a friend with one to help out
Various 3D parts. The models for these are available here.
Custom PCB board.
With all the materials needed in hand, it is time to get on with the build.
The first thing to do is print out the 3D part you’ll need for this build. We have included the models above, but you can also find them here.”
