So I was browsing Thingiverse for LEDs Jigs and found this great JIG designed by Mohit Bhote https://www.thingiverse.com/thing:3147406
I look at it and I was like I have to make an LED tower with this! so I did.
Thanks UTSOURCE.net to offer electronic components for this project! you can check UTSOURCE.net they deal in all kinds of electronics components like for example all the Components used in this project!
Watch the video for the tutorial-
it covers the Basic Built which is the SOLDERING PROCESS
after the soldering process, we get this huge 10 Levels LED TOWER
I soldered these led according to this scheme-
Positive terminals of all these LEDs are connected common and the Ground terminal of each layer is separated.
WHY? because the Ground pin of the LED Tower will connect with the Collector of the Transistor and the microcontroller will control the Base of the Transistor.
Each LED LAYER has 18 LEDs in total connected in parallel, a normal Arduino I/O pins is not powerful enough to drive this so using an external MOSFET is ideal.SETUP
so I made this PCB which have 10 2SC6120 NPN Transistor connected in "Transistor as Switch" setup along with 20 10K Resistors.
I made it in Orcad cadence and then etched it with the Generic etching solution (with Ferric Chloride Powder)
after assembling the circuit, we just need to hook it up on a breadboard
with an Arduino board, In this case, an Arduino micro.CODE-
Upload the sketch attached
For powering this setup, I'm using 3.7V Lithium io cell,RESULT-
ok so here's the result!
this is how you can build and program an LED TOWER, it's like an LED CUBE but a much easier thing to make and it also requires less led.
well yes, we can program or alter the code in order to get various patterns in animations...
