DIY 7 Segment Display With LED & Arduino | Arduino LED Interfacing | DIY 7 Segment Display From 7 LED's

Making 7 Segment display from 7 LED's & controlling them with atmeg328p & displaying numbers

• Arduino UNO
• 5 mm LED: Red x 6
• 5 mm LED: Green x 1
• Breadboard (generic)
• 9V 1A Switching Wall Power Supply

This project is about making a 7 segment display at home from the readily available supplies.

We are going to make seven segment displays from seven LEDs. To display numbers from zero to nine.

Seven LED's to make Seven segment display. PCB/ Cardboard to fix LEDs. A breadboard for connections. Some Wires for interconnections. Power Source. A Microcontroller for controlling.

Now we will insert LED into its specified slot. We will use the cardboard templet to mount the LED properly. We will connect them first from the center then to the outward.

We are done with the connections. Now we will check whether all LEDs are properly connected. Before connecting them to Microcontroller. Now we will check which pin is for which LED. Let's connect the microcontroller to the computer. And upload the code. Let's test the code & connection. Yes, it is working. Now we will tweak the code to display numbers. We will cover LED with a cardboard template cut in the shape of a seven-segment.

Now we can see, we have made a seven-segment display with seven LEDs. And it is working fine.
