多数のLEDを手軽に光らせたいと思ったことはありませんか? 我々はたびたびそう思います。そんなときに使うのがArduinoとTLC5940です。 TLC5940はテキサスインスツルメンツのLEDドライバICで、1チップで最大16個のLEDを制御できます。各LEDを定電流で発光させる ...

今回は、Arduino UNO R4を使ってLEDを光らせる方法を解説します。 ELEGOOのLearningキットE3という電子工作キットを使った、初心者でも簡単に遊べるレシピです。 完成品のプログラムも載せているので、安心してください。 ぜひ、最後までチャレンジしてみて ...

今回は、Arduinoでのフォトリフレクタの使い方についてご紹介します。 フォトリフレクタはライントレースロボットにも使われるセンサーです。 使い方をマスターすれば、ロボット制御の理解もより一層深まります。 赤色LED* 抵抗* ジャンパーワイヤー ...

Here is a 3D light show that will astound you with its combinations. Inexpensive and easy to make thanks to an Arduino controller, the design enables you to play with the existing effects and, most ...

In this project, we're making a cool 4×4×4 LED cube with Arduino Nano. LED cubes, also known as LED Matrix, can light up your room, study space, or Maker area giving it a awesome cool look. Moreover ...

I have spent at least an hour almost every day since the 80’s advancing my knowledge in electronics. Recently I brushed up my knowledge on LED fading secrets and attained something pleasant. Now, I’d ...

In order to recognize colors from a video input, this project employs a Python script using OpenCV. A byte of data is then sent through the serial connection between the Arduino board and the local ...

This repo contains code for implementing a simple LED chaser using an Arduino (or similar microcontroller), made for friend creating a replica of the flux capacitor from the movie Back to the Future.

This is tutorial number 1 from our series of Arduino tutorials and in this part I will talk about blinking an LED using the one already available on the Arduino Uno board or using an external LED to ...

The Julia programming language is a horrible fit for a no-frills microcontroller like the ATMega328p that lies within the classic Arduino, but that didn’t stop [Sukera] from trying, and succeeding.

Sure, the physical build itself looks great, but it’s what [Michael] did with the firmware that impresses us the most. He’s using an Arduino Mega to drive the 7x7x7 cube and manages to squeeze out ...
