Today I finished the CAD jejeje , I realized that the problem with my motors not working was the amps, not the voltage. I spent like an hour trying to see if it was a coding issue, and it turns out I was using a 9V alkaline battery, and it doesn’t provide enough amps :C. I made some battery holders that didn’t work that well. I’m going to work on the journal, the readme, and the website today (if I survive), and I couldn’t make a battery holder that actually works… I don’t recommend wasting an hour of your life doing it.

the bot looks so done with everything lol… he’s like “Let me rest..”
do you try to use a Li-Ion 2S o 3S battery and a buck converter?
@Cipher012 I DID! The project is thinked for LiPo 7.4V 2S, I used it at the start, but just works 3 hours
I think I’ve found the problem: it’s the power management. You are powering everything—sensors, microcontroller, and motors—from the same source, which results in high power consumption. Here are my actual recommendations: A) Separate power management: power the ultrasonic sensor and microcontroller using a 1S battery (as before) and an independent buck converter, while powering the motors and OLED display with a 2S Li-ion battery. B) You could use a mixed 2S2P Li-ion setup, consisting of two packs of two batteries connected in series, with those packs connected in parallel. In both cases, make sure to maintain a common ground.
@Cipher012 OMG u are so smart, I’ll try it THANK U A LOTTT <3
