I need help asap!
I am working with a dual H-bridge L293D and a 12V motor with 90 rmp. My goal is to spin that motor clockwise and counterclockwise to spin my lead screw.
The problem: the motor’s speed isn’t that high.
I have connected my 12V adapter to the H-bridge, VCC to 5V in arduino GND to GND, pin 9 to M1A and pin 10 to M1B. Then my P2 for M1 positive and negative is connected to my motor. The code compiles well and it spins but I realized that when I remove the adapter the motor functions in the same speed. Which I assume it means the motor is running on the 5V provided by the arduino.
What am I doing wrong??
