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 ...

Quality software development examples can be hard to come by. Sure, it’s easy to pop over to Google and find a <code> block with all the right keywords, but having everything correctly explained can ...

First of all, you need to download the Arduino IDE on your computer from its official site so that you can write the code and upload it to the Arduino UNO board. Now follow the below steps to do the ...

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 ...

[Chris] wrote us to share a neat technique he has been using to program the Arduinos he uses in his projects. He likes to build bare bones Arduino clones rather than sacrifice full dev boards, and ...

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 ...

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 ...

I had the idea of building this Arduino icicle lights project during the making of the light dimmer circuit and the result can be seen below. Is not a complicated project so it can be done easily by ...
