![]() ![]() ![]() Raspberry Pi – This will be the brain of our system. ![]() To put the full system together, you’ll need the following parts:īreadboard – This will act as the circuit board for our system, connecting all of our components so they can interact with one another. Let’s start building our system! What you’ll need This is the first post in a three-part series about that workshop-today, we’ll cover how to set up a basic circuit that controls LEDs via the Raspberry Pi. If we are far enough away from the sensor, a green LED will light up if we get closer, a yellow LED will light up and if we get too close, a red LED will light up and a speaker will emit a warning sound. How does this distance measurement system work? Essentially, we will measure the distance between an object and an HC-SR04 sensor. In September 2019, I hosted a workshop at try! Swift NYC where we used a Raspberry Pi to build a distance measurement system for an autonomous car. From robotics to home automation, you can use it to do just about anything. The Raspberry Pi is a fun little device that everyone can learn from. ![]()
