Question regarding stand-alone MCU

Projects General Guidance
1

Hello-

I hope you are all having a good day so far and I want to thank you for taking the time to read my question.

I programmed my Arduino to control two motors using a H-Bridge on a breadboard (pretty simple set-up). I am also using a bluetooth module HC-05 to control the motors via an app I created for Android. The next step in my project is to shrink my project onto a PCB board. I followed the instructions I found on this website on how to embed a standalone MCU and it uploads the program. When I attempt to integrate my newly "programmed" MCU into a breadboard (following the same setup I used initially with the Arduino, BT module, and H-Bridge) the motors do not function when I attempt to activate them via the same app I made for my phone that I used before when it was the Arduino and all other components. Any ideas on why it is not working?

Thanks for reading and thank you in advance for answering!!

You need to provide more specific information. What MCU are you using?

I have had no problem getting Atmega328s working on Veroboard circuits with their 8MHz internal oscillator using this Tutorial

However I have no idea from your description exactly what you have tried.

It would be a good idea to make drawings of the working circuit and the non-working circuit and post photos of the drawings.

And post your program.

Have you tried a short test program to make sure your standalone circuit can receive bluteooth data properly?
