In this circuit, the infrared emitter IRED1 is modulated by connecting its anode (A) to ~38kHz signal yielded by D9 of the Arduino Uno (TP1) while its cathode (K) to a ~1kHz signal available at D8 of ...

Here he’s created three touch sensors, connecting them to the Teensy microcontroller with two resistors each. The larger resistor (looks like 4.7 megaohms here) sends a signal through the copper ...

Normally, this problem is most easily solved by throwing a temperature sensor on the I2C bus — these sensors are cheap and readily available. This isn’t about connecting a temperature sensor ...

I2C protocol makes it easier to connect more ICs using only 2 wires SDA and SCL and allows communication between them at relatively low speed. The I2C bus or TWI (Two Wire Interface) allows a single ...

By connecting a foil sensor to an Arduino, you can detect significant shifts in electrodermal activity during questioning, akin to a basic polygraph test.

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

Learn how to connect your Raspberry Pi to the Arduino Cloud and control Raspberry Pi GPIOs using Python to create visual data representations ...

The Pressure Sensor Module incorporates a material called Velostat with the Arduino. This material adds more resistance when more pressure is applied to the material. This module also uses the RGB LED ...

Photo: John Biggs/Gizmodo. Luckily, Arduino’s own cloud services make it surprisingly easy to code for the Oplà. I opened the box, plugged the board into the Carrier, and then connected the ...
