Using Rotary Encoder with Arduino Uno R3 and OLED Display

In this tutorial, we will demonstrate how to use a Rotary Encoder with an Arduino Uno R3 to control variables and interact with an OLED display. Rotary encoders are popular input devices used for setting values, navigating menus, and controlling electronics projects.

TME EDUCATION

TME Education is a programme that aims to promote and popularize electronics and technology-related knowledge around the world, especially in regions, where the access to proper training is limited. The initiative was launched by Transfer Multisort Elektronik, one of the leading global distributors of electronic components, located in Poland.

Control LED Brightness with XIAO RP2040 & OLED Display | Push Button Tutorial

In this project, you will learn how to control the brightness of an LED using two push buttons and display the brightness level as a percentage on an OLED display. We will use the XIAO RP2040 microcontroller, which is compact but powerful, making it perfect for projects like this.

Arduino Distance Measurement with Audio | Ultrasonic Sensor + DFPlayer Mini

In this tutorial, we will explore how to use an ultrasonic sensor to measure distance and trigger audio feedback using the DFPlayer Mini module.

Smoke Detector with XIAO RP2040 & MQ-135 Sensor | Audio Alert System

This project teaches you to build a smoke detector that triggers an audio alert when smoke is detected. Using the Seeed Studio XIAO RP2040 and the MQ-135 smoke sensor, we’ll create a compact system capable of detecting smoke and playing an alert through the DFPlayer Mini and speaker.
