Hey guyss, COMPLETE NEWBIE RIGHT HERE
I just bought a 15A dual motor driver off Amazon recently.
Link right here-
The driver didn't come with a lot of information unfortunately. But I'm trying to make it work with two 500W Brushed DC Motors with PWM inputs from my Arduino Uno controlled by a joystick. It worked at first ,but then all of a sudden the whole thing doesn't work when I changed my power supply to a bigger one(PS 2042-10B).
The circuit set-up and coding are replicated straight off this tutorial that I've just read. So you can find the coding and schematic details in the site.
Link heree-L298N Motor Driver - Arduino Interface, How It Works, Codes, Schematics
Since everything's busted, I try to work it with a small 1.5A DC Motor first.
Here's the connection:
GND = GND(UNO)
PWM1 = Pin 4
DIR1 = Pin 9
+5V = 5V(UNO)
POWER = +power supply, GND = -power.s, MOTOR1(+,-)= motor
The motor spins immediately when I connect the +5V but the PWM signal doesn't seem to work.
I assume the driver current bypasses the signal current from the UNO.
