CIRCUIT DESIGN

I used Output device in Fab Academy circuit. I modified a INPUT potentiometer.

First of all, I used a design the Academy circuit and design it in Eagle

CIRCUIT MILLING

PROTEUS SIMULATION

I simulated in Proteus, and I used L293 stepper driver, because the driver A4953 isn't in Proteus simulator. Here result:

And here the Proteus simulation:

The circuit work this: A value of potentiometer is the time that the motor move. If the value is high, time is more, if the value is low, the movement is short. After the time motor movement, the motor will stop.

This is the circuit:

And how it works:

DC MOTOR

The next program, I used the same board but only the one Bridge A4953 for DC Motor.

HOW IT WORKS

DC Motor rotates for three seconds clockwise and waits two seconds and turns counterclockwise, waits two more seconds and turns clockwise again for three seconds.

CODE


int a = 0;
int b = 1;

void setup() {

pinMode(a, OUTPUT);
pinMode(b, OUTPUT);

}

void loop() {

  digitalWrite(a,HIGH);
  digitalWrite(b,LOW);
  delay(3000);
  digitalWrite(a,LOW);
  digitalWrite(b,LOW);
  delay(2000);
  digitalWrite(a,LOW);
  digitalWrite(b,HIGH);
  delay(3000);
  digitalWrite(a,LOW);
  digitalWrite(b,LOW);
  delay(2000);
}
