I started my first project. I would like to create a connected light for my daughter. I'll design all from scratch (electric diagram, pcb creation, 3d design, ...).
I would like to have a feedback about my electric diagram. Any feedback (about the choose of parts, about the quality of the diagram) will be helpful. However I can change some parts but I already bought all mosfets and the L7805ACP.

I decided to use a L7805ACP and some capacitors to convert 12v to 5v (used by the esp32). Each color (red, green, blue and white) will be drive by a MOSFET IRLB3034PBF.

I added a simple led when the lamp is plugged in.

There is the electric diagram.

Thank you very much for your feedback

- Sat Mar 19, 2022 10:53 am #94012 Is there a pcb design option with your software? I used Easy EDA to design my pcd as it has a pcb design option.

Thank you for your reply.
The 5V will be connected to 5V and GND pin headers (https://docs.espressif.com/projects/esp ... tc-02.html).
I'm using Eagle to create the electric diagram. I'm pretty sure that I can create the PCB from this software.

Best regards,
Sylvain
