About this project

One Board to Rule Them All

It's a DC Motor Testing kit, also possible to convert in to some motor controlled project.

It was made long ago to demonstrate kids about DC motor control.It has pinouts for one 4 pole stepper, one servo, 2 DC Gear Motor control.

Motor Controller

Hardware

Three user switch

Three Input Status LEDs (RYG)

4 Red Output Status LEDs

10k Pot for Position Control

4 Outputs driven by L293D for Stepper Motor Drive

Small Servo Control/Power Terminals

Firmware

Arduino programmable according to following pinout.

Atmega32 AVR Arduino

Also programmable in C/Assembly in Atmel Studio. Any GPIO can do the functions!

What Makes The Difference?

There are 32 GPIOs vs Uno has 23 GPIO:

8 ADCs vs Uno has 6

3 Interruprs vs Uno has 2

Separate I2C pins

Separate Reset pin

This is not a project, just a project snippet!

Code

Mix of AVR and Arduino Style Arduino

Programmed in Arduino IDE

#include <avr/io.h>
#include <util/delay.h>

// Step Sequence Generation for 4 Pole Stepper Motor !

int z =250;
int main()
{
DDRB |= 0x07;
PORTB &= ~(0x07);
while(1)
{
  for (int i=0;i<16;i++)
  {
    for(int j=0;j<3;j++)
    {
PORTB |= (1<<j);
_delay_ms(z);
PORTB &= ~(0x07);
    }
}
  
_delay_ms(500);
for (int i=0;i<12;i++)
  {
  for(int j=2;j>=0;j--)
    {
PORTB |= (1<<j);
_delay_ms(z);
PORTB &= ~(0x07);
    }

  }
}
 return (0); 
}
