Hi all, I am currently working on this robot with the guidance of the following website
"https://circuitdigest.com/microcontroller-projects/obstacle-avoiding-robot-using-pic16f877a"
The circuit diagram is as shown below
The L293D motor driver module he used looks something like this
while mine is exactly this module
In the circuit diagram there is M1 ChA, ChB, M2 ChA, ChB while mine has PWMA, PWMB, DIRA, DIRB.
1. Do the 4 pins have the same functions (meaning that they appear in different names)? As in M1 ChA is PWMA, M1 ChB is PWMB and so on
2. May I know how do I connect this to a PIC16F877A using a breadboard? Is it the same as the circuit diagram provided?
3. Is there a datasheet for my module? I have searched "MRL293 Datasheet" in search engines but I failed to obtain any datasheets.
Thank you
