Here is a traffic light system based on Arduino that can be used in a 3-way ond 4-way intersections. It has an additional blinking orange led that is used to signal when the pedestrians can cross the ...

Now that you've seen how to blink your Arduino's LED, we'll use one final, slightly more complex example: we'll use a third-party UNO breakout board and an external traffic light sensor board to ...

An Arduino can be ... it via a corresponding LED. At least when you go directly to jail you'll have a cool creation to pass the time. Build a working model traffic signal. It not only displays ...

The Arduino sketch sets up the serial connection and then listens for incoming traffic. Whenever it receives a non-zero character an LED will blink. On the server side of things you’ll need to ...

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 ...

To make things a little easier on yourself, Arduino shield-maker 1Sheeld shows off how to hack a clock to change color depending on traffic conditions. The idea here is to use a cheap clock from ...

8×8 LED Matrix modules are now widely available, and fortunately they are easy to use with our favorite Arduino microcontroller. 8×8 LED Matrix module have many applications in real life, such as ...
