This PCB is a metal detector. The circuit is very easy and I will do my best in this tutorial to explain to you how it works. I use real examples and animations in the video below so you will understand everything. The PCB is interesting because it already has the coils on the board made with ... view more

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.

As John Keefe notes in his project writeup, at-home pulse oximeters — which monitor the oxygen saturation in your blood — have been selling out due to the COVID-19 pandemic. While you could try hunt around and find one, he decided to instead make his own device using a SparkFun Pulse Oxi... view more

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
