An API that lets you display numbers and letters on Laser7Segment RGB LED displays that are available from tindie

You can find the Open Source hardware PCB design and Gerber files here too as well as the DXF laser cut design files

The downloaded code should be added to your arduino IDE libraries folder, and the library requires the Adafruit NeoPixel library for it to function.

To include the Laser7Segment library in your project:

#include <Laser7Segment.h>

You can then initialise the display with the following line that includes the number of Laser7Segment digits and the GPIO to control them:

Laser7Segment disp( 5, 4 );

You then start the display with the bebin method, passing the brightness:

disp.Begin(80);

The you simply pass the display the String you would like displayed and a color:

disp.DisplayText( "1234", disp.Color( 255,0,0) );

Enjoy!

I love designing, making and releasing our projects as open source. I do it because I believe it’s important to share knowledge and give back to the community, like many have done before me. It helps us all learn and grow.

That said, a lot of time, effort and finances have gone into designing and releasing these files, so please consider supporting me by buy some of my TiinyPICO products:
