Using an Arduino, IR LED, and a matching sensor, we are able to detect objects by pulsing the LED, and reading the sensor's response.

Learn how to use a BNO085 breakout board with an ESP8266 to read movement and orientation data using the Arduino IDE.

This article serves as an introduction to ultrasonic sensors and explains how you can get them up and running in no time using an ESP8266 development board.

Learn how to connect a small keyboard to an Arduino, how the keypad functions in theory, and how you can implement that theory in software.

This article describes how to direct a Raspberry Pi with any conventional IR remote control and how to send IR signals from a Pi to control other devices.

Using an Arduino Uno, IR emitters and receivers, and the IRemote library we build a simple circuit that can send or receive standard remote control signals.
