Intro: 5 Digit Arduino LED Matrix Binary Counter
This project was developed by using a 5x7 LED Matrix ( LJ7071-22) and an Arduino Nano. From the 5x7 LED Matrix, draw the 5 common cathode column pins & the 4 common anode row pins so that you can form each digit of your counter.
Step 1: Bill of Materials
1 Arduino Nano
1 5x7 LED Matrix (LJ7071-22)
1 USB-mini to USB-A Cable
Step 2: 5x7 LED Matrix Configuration
Check the configuration of your 5x7 LED Matrix and as its pins are distributed.
Step 3: Preparing the Installation of Your 5x7 LED Matrix
Before installing the 5x7 LED Matrix, prepare the area with a pair of pieces of foam tape two sides glue.
Step 4: Install the 5x7 LED Matrix
Insert the 5x7 LED Matrix in your Arduino nano by observing how you should join the pins from 5x7 LED Matrix to the Arduino nano.
