If you haven’t read the previous tutorial on multiple sensors, you may want to read that one first: Multiple HC-SR04 with Arduino using interrupts With using multiple interrupts, there’s the disadvantage that the sensors may interfere with each other, when facing the same direction, and crossing each others line of sight. Also, since most Arduino […]
If you need to measure distances or detect objects, but you don’t have a large budget, the HC-SR04 Ultrasonic Sensor may be something for you.
When using autonomous vehicles, it’s important to be able to detect obstacles fast and efficient. The ideal way to do this, is by using Lidar, but that may turn out expensive. A much cheaper way is by using multiple ultrasonic sensors like the HC-SR04. This tutorial explains how you can use multiple HC-SR04, reading and […]
