I would like to try running things using an ESP32-based board with Arduino. When it comes to running microcontrollers, the classic starting point is the "blink"—making an LED flash on and off—which is ...

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

在之前的项目中，我们已经展示了如何使用Arduino来控制LED矩阵。但是，如果您的项目只需要显示数字，那么最好使用七段数码管。这些数码管看起来像复古的数字闹钟，只需要七个LED就可以显示出数字。本指南将向您展示如何完成这个工作。 七段LED数码管的 ...

Let's use Arduino to make a light that turns on automatically only when someone approaches and turns off after a while.This ...

This is just a fun Arduino project that uses leds connected in circle as a ring to produce a rotation effect. You can adjust the spinning speed with a potentiometer and you can also set a minimum and ...

Regular candles can be awfully boring at times. They can only produce one color and the flicker is so… predictable. They can’t even be controlled by an infrared remote control, not to mention the ...

In the last installment of The GeekDad Arduino Guide, I introduced you to the Arduino hardware and why it is so cool. Now, let’s start actually using an Arduino. How do you get started? Well, first ...

Explore two new Elektor Academy Pro STM32 programming courses, featuring MicroPython and Arduino, as part of the Embedded ...

Arduino Micro has some extra leds that it is tricky to programme. Like almost all Arduinos, has a built-in led – the green one on the left in the photo. And it has a pair of yellow leds – called TX ...

You can get a long way just using the matrix library, but there is another library, ArduinoGraphics, that has additional functions that make the LED matrix really useful. However, at the time of ...
