Has anyone used the L293D Motor Driver Shield & Arduino?

in Support

I am having issues loading the UNO with the firmware. Can anyone tell me what software I can load onto the UNO in order to operate the L293D? I tried to use the SelectorFirmwareMK4.ino.with_bootloader.hex but I continue to get and error. "Arduino can only open its own sketches and other files ending in .ino or .pde.".

I also found this doc that helps explain the pin out. https://playwithcircuit.com/l293d-motor-driver-shield-arduino-tutorial/ So the question becomes are we programming the pins on the Arduino or the L293 Motor shield? And what are they looking for regarding the label of the pin. Found this code on another site. Looks like the L293 has a forward and backward pin out. Is that what chameleon has as well?

Replying to

I have a Creality K1C. As of now I have figured out what pins do what on this L293D motor driver. If I could understand what the program is doing with the pins, I would be able to match them up. I understand that the ext and sel are the motors. Obvious the extEnable is to enable the motor. I assuem the extStep is to turn on one directions and extDir is to change directions? Trigger is the switch. What is the s_Limit and Filament for. Are there more than one switch? Not sure what they need to trigger. #define extEnable 3

#define extStep 10

#define extDir 9

#define selEnable 3

#define selStep 5

#define selDir 6

#define trigger A3

#define s_limit A4

#define filament A5
