The SHARP GP2Y0A710K0F is a relatively easy to use IR distance sensor with an extra long range of 100 – 500 cm. This extra long range makes it a good alternative for ultrasonic distance sensors.

We will make a homemade ultrasonic distance sensor and see how these modules work. The working principle is quite simple but the circuit could get a bit tricky. We send a ultrasonic wave with the transmitter speaker, the wave hits an obstacle and bounce back to the receiver speaker. We calculate ... view more

In this tutorial we will make a homemade lidar. Is not as good as commercial lidar sensor, but it would be good enough for some small robot to avoid obstacles. I will show you what is a lidar sensor, how they work and how I’ve made a homem... view more
