Universal board for LED control.
- Atmega8/328 on board with programming connector
- PCA9685 for 16 channel PWM up to 1.5kHz (eye-safe frequency), 12 bits per channel
- cheap ULN2003 with paired outputs for 1A per channel (2-3 meters of RGB 5050 strip per connector)
- or SOT23 MOSFETs if you need more power
- BT05 bluetooth module or MAX485, control by wire or wireless. DMX512 is possible.
**2021-03-24:** Current version of program is available in attachment. Does not support yet buttons to change brightness.
**2021-02-18:** New PCB design, which is aligned with PCB for "Christmas Tree LED Wiring" project. Now headers are used for connectivity.
The lates update is replacing IRF9540 with AO34I9L in tiny SOT23-3 body. I ran a test on a prototype for a few hours with maximum brightne...
<p>Decorate your house today with this Raspberry Pi (Zero) controlled shooting star.</p>
<p>Control each LED individually with the I²C 16 I/O expander.</p>
<p>By programming the Raspberry Pi (Zero) you can animate the shooting star as you wish.</p>
<p>The dark PCB makes it stand out even more.</p>
<p>You can order these PCBs at <a href="...
<p>This a project that i have created to celebrate this year christmas!<br />The project consists in a PCB format as a Santa Claus Dabbing with some leds to hang on a christmas tree.<br />Is it controlled by a microcontroller AtTiny and two shift registers to blink all the 16 smd leds.</p>
<p><br />This idea only can be possible by the <strong>excellent</strong> quality of the factory&nb...
