This project is very interesting because it shows the sequence of all letters of our English alphabet. That is, the project generates capital letters from the A to the Z based on Arduino code and showed by an alphanumeric display. I'm using a common cathode alphanumeric display and an Arduino Uno in order to constructing this project. Use the following link so that watch a video of the project working: http://www.youtube.com/watch?v=jmZ5V43CFf8
Step 1: Bill of Materials
1 Photo shield for Arduino Uno (PCB only)
1 Common cathode alphanumeric display (14 segments)
14 Resistors of 220 Ohm, 1/4 Watt
1 Header pin male of 1x40 pins
1 Arduino Uno
1 USB-A to USB-B cable of 3ft
Required tools and supplies:
Needle nose pliers
Step 2: Project's Diagram
Firstly, you should check what you are going to do then observe the diagram of your project.
Step 3: Install the Alphanumeric Display
Observing your diagram, install the alphanumeric display on the PCB and solder its pins on it.
Step 4: Install the Resistors of 220 Ohm
After installing the alphanumeric display, install the resistors of 220 Ohm among the alphanumeric display and the pins marked in the project's diagram. Note that I first connected the resistors and then the pins to interface to my Arduino hardware. However, being better that you first install the pins and then the resistors because it's easier for doing all connections and solder to the pins.
Step 5: Separate the Pins That You Will Need
Take the component 1x40 header pins male and then cut 1x15 pins so that you can later separate those 15 pins in 1x3, 1x3, 1x6, and 1x1 pin that are the pins that you will need to connect to your Arduino platform.
Step 6: Insert the Pins Reserved
Insert the pins reserved in your Arduino hardware Note the pins are 1x6 ( A0, A1, A2, A2, A3, A4, A5), 1X3 (2, 3, 4), 1X3 (8, 9, 10), 1X2 (12, 13), and 1x1 (GND).
Step 7: Match the PCB With the Pins Installed
After inserting the pins into your Arduino hardware, match the PCB with those inserted in the Arduino and then solder them.
Step 8: Dismount Your PCB
Dismount your PCB after soldering the pins inserted into it and observe how it looks.
Step 9: Complete Your Project
For completing your project, mount the PCB newly on your Arduino platform and with help of your USB-A to USB-B cable you can interface the computer and your project for uploading the Arduino code for this project by doing copy the following link:
