Unfortunately PWM control does not work on the L298N unless you use a voltage higher than 5v

I believe you're right... the L298N in my Chester robot had 2 18650 cells... seemed to work fine with PWM.

I'm also having an issue with bluetooth: the HC-05 connects, but does not receive or transmit data evn though the connections are correct.

If you know how to fix this, please tell me.

I don't use bluetooth, and you rejected my earlier suggestion to going to WiFi.  If you look at any of my vids on this forum,

I punt all Arduinos, use either a WeMos or NodeMCU ESP8266 which includes the WiFi built-in and host a website on the bot that serves up the R/C page on any device... PC, tablet, phone to control the bots.

Even usable on ESP-01S - Quickest Start Guide

@valerio - Besides... Bluetooth is only good for 32 feet or so.  That doesn't even reach to the refrigerator for the beer.  🤣

@inq A lot less if walls etc are in between.

First computer 1959. Retired from my own computer company 2004.
Hardware - Expert in 1401, and 360, fairly knowledge in PC plus numerous MPU's and MCU's
Major Languages - Machine language, 360 Macro Assembler, Intel Assembler, PL/I and PL1, Pascal, Basic, C plus numerous job control and scripting languages.
My personal scorecard is now 1 PC hardware fix (circa 1982), 1 open source fix (at age 82), and 2 zero day bugs in a major OS.
