Hello, and welcome to this tutorial on how to light a seven segment display! This will be without code, so you don't have to know C++ to do this.

Supplies

• 220Ω Resistor

• Breadboard

• Arduino Uno Rev3

• 7 Segment Display

• 10 Male to Male Jumper Wires

• First, place your 7 segment display on the breadboard.

• Next, take 8 jumper wires and connect the LED pins to the negative rail.

• Then, take your resistor and connect either common (middle) pin to the positive rail.

• Finally, take the other 2 jumper wires and connect a ground to the positive either the 3.3V or the 5V to the negative rail. Flip the two if you are using a common anode.

Done!
