Summary of Arduino LED Scroll Bar using easyEDA
This article details the construction of a custom LED Scroll Bar featuring ten independently flashing segments. The project utilizes an Arduino Nano paired with a custom-designed control board and keypad to manage various lighting patterns. The process involves cutting LED strips, soldering connections with Dupont lines, and designing the control circuit using EasyEDA software before manufacturing the PCB.
Parts used in the LED Scroll Bar:
- LED strip
- Arduino Nano
- Dupont line
- Control board
- Keypad
- Power regulator (AMS1117-5.0)
Today I want to make a LED Scroll Bar as is shown in the picture above. Ten LED strips can flash in different effect by using a control board.
Components
LED strip, Arduino Nano, Dupont line and a control board.
How to make it ?
Step 1)
Cut the LED strip into 10 pieces with each LED arbitrary number.
Then, weld the traverse at an interface of the LED strip. Here I prefer using Dupont line to connect.
Step 2) Design
Make a control board. A control board is the pattern to control the flash of the LED strips. Aided by Arduino Nano and equipped with a keypad, we can control the LED strip to display different pattern.
Step 2.1) Design Schematic.
EasyEDA is a free EDA tool suite, it includes Schematic Editor, PCB layout, it has integrated a large number of component libraries, so you can feel easy to find the desired parts.
This is my Schematic shown in the picture below.
Notes: The voltage of the LED strip is 12 V with Nano 5V. Please remember to add a power regulator such as AMS1117-5.0.
Step 2.2) PCB Layout.
Step 2.3) Make a sample
After finishing designing the PCB, you can click the icon of Fabrication output above. Then you will come into the page of download gerber files and make sample, and are required to fill in some information such as PCB Thickness, Color, Qty of the plate. Next, add it to the shopping cart and after the payment is done, it is finished.
Step 2.4) Take delivery of the PCB
What a good PCB!
