A PCB Badge which is also an LED Chaser using the 555 Timer Integrated Circuit which I designed for my event!
I made this to help other students like me learn about what ICs were and how they work! And also to have a really cool light up badge which I can show off to everyone!
All about the hardware and design behind this project!
The schematic was made in EasyEDA' pro editor.
The PCB was also made in EasyEDA's pro editor. It uses JLCPCB's colourful silkscreen printing.
These renders were done in Fusion 360
The BOM of this project is inside the "BOM" folder in this repo in .csv format. The PCB is the only expensive part of this, the other components cost just under 1 USD.
Take the PCB and solder in all the components keeping in mind the side it has to go through.
Then connect a 9V battery using the 1x2 connector pins..
Adjust the potentiometer to control the speed of the LEDs!!
I had no trouble with this project because it is a fairly simple one but it did help me learn about the EasyEDA editor and also JLCPCB's silkscreen technology!
