By combining 49 of them he’s put together a soda bicarb diode steering circuit for a 7-segment display capable of showing the digits 0 to 9. He takes the idea for his diode from electrolytic ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

The seven segment we liked best was still quite ... Join us after the break to see how the display and the controller circuit are made. 14 LEDs, as bright as you can get without generating heat.

Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

Save guides, add subjects and pick up where you left off with your BBC account. Output devices such as motors, solenoids, bulbs, buzzers, relays, LEDs, and 7-segment displays are used in many ...

This is what it looks like in action: My model uses the car's OBD-II port to connect to an Arduino microcontroller, which is programmed to display the car's speed on a 7-segment display.
