Hi guys,
I got my Bipolar, 200 Steps/Rev, 35x28mm, 10V, 500mA motor and connected it to the L293 chip, as shown here
Here's how it looks like:
and the code
#include <Stepper.h>
const int stepsPerRevolution = 200;
Stepper myStepper(stepsPerRevolution, 2,3,5,6);
void setup() {
myStepper.setSpeed(100);
}
void loop() {
myStepper.step(stepsPerRevolution);
delay(500);
myStepper.step(-stepsPerRevolution);
delay(500);
}
Yet there seem to be two problems
-
the L293 chip is getting very hot, too hot to touch. Is that OK?
-
the motor is also getting noticeably warm.
I'm powering them from an adapter at 9v / 600mA, if I run them at 4.5v , it doesn't get hot, yet of course, the power of the motor is not the same. )
Thanks
