Today was a lot of off screen learning about electronics. I used chatgpt to explain what the different parts of a circuit and pcb are, and then figured out the different parts that i needed to add based on its explanation of different components and voltage and current.

I realized that you can’t actually power a speaker or motor directly from the ESP 32. In the case of a motor, the intermediate is a mosfet (picture), and it allows the esp to open and close a gate that supplies higher power to the motor than what the ESP can supply. I’m still a super foggy on how different modules interact with the pcb and and if they are separately connected with jumper wires. These modules and parts are almost on a need to know basis in my brain, but I feel like I’m learning.

Finally, I know that I didn’t put in a ton of time today, but today was super stressful, and after a half day tomorrow, I’m actually going to meet some cool older tech entreprenuers. They aren’t working on companies anymore, but they are coaching startups, so i’m SUPER excited to talk to them!!! Anyways, after that, I should have time to study and do this over the long weekend. Yay!
