Hello everyone, i'm fairly new to RAMPS 1.4. I'm currently working on a project and i need some advice. My project consists of using the Arduino MEGA + RAMPS 1.4 to control 4 stepper motors via bluetooth (HC-05). I found there are different ways to do this but i don't know which set up is easier or if i understand them correctly.
1. Serial1 on pins 19 (RX) and 18 (TX), (on ramps Z-Min and Z-Max endstops pins), which means that i have to use the voltage divider to regulate the 5v(from the RAMPS) to 3.3v(Rx pin on the bluetooth)
2. Serial0 on pins D0 and D1, saw in this tutorial
3. Hook up the HC05 to Arduino UNO and connect it to the MEGA
I'd appreciate any advice that you can give and i wish you all a good day
