Hey!I am building and rc car TX and rx system which I am applying
to my dead old rc car with servo as steering system
right now you dont have any content in your repo! we need to be able to see what you made, so please update this to include all the files as well as a clear readme so we can see what you made!
Devlog #2— WiringWired HC-05 to Arduino (RX/TX with a voltage divider since HC-05 is 3.3V logic). Connected motor driver to the existing motors and Arduino digital pins. First power-up: no smoke, good sign.
Devlog #1 — Diagnosing the patientDug out my old RC car that’s been dead for a while. Popped open the chassis to check what’s actually broken. Tested the motors directly with a battery — they spin fine, so the problem is isolated to the RX/TX board. Decided to scrap the original electronics entirely and give this thing a new brain: Arduino Uno + HC-05 Bluetooth module, controlled from a generic Bluetooth RC app on my phone instead of the original remote
