CYBORG DIY : product compatibility?

Alexsense · January 10, 2019, 8:11pm

Hello guys !

I am willing to create a device that can indicate the north by vibrating when the device is pointed towards north.
I have no exp in elec but I want to try my best to do it. This is about how I can do it (barely) alone thats exited me.

I have found 2 products : RB-See-403 and RB-Oel-14.

I am asking you guys if the two product are compatible and How I can link them together ?

Thanks by advance for all the help or any advice to lauch me on this path !
Have a great day,
Alex

Hey!

That’s a nice project! You will definitely need a micro controller to do that. If you do not have any experience in programming, I suggest that you take a look at this tutorial: https://community.robotshop.com/tutorials/series/arduino-5-minute-tutorials

You can buy an Arduino here:

It is one of the easiest platform for programming.
You can also find the code for the compass here:

github.com

blaisejarrett/Arduino-Lib.HMC5883L/blob/master/examples/Compass/Compass.ino

/*
 *  Reads the direction your compass sensor is pointing in degrees
 *  The sensor is pointing North when the X axis marking is pointing North
 *
 *  Place the sensor on a flat surface and avoid anything magnetic that
 *  may skew the results.
 */


#include <Wire.h>
#include "HMC5883Llib.h"


Magnetometer mag;
bool fail;

void setup()
{
    Serial.begin(57600);

Now, for the motor. You don’t want to power it directly with the arduino outputs as they are rated at 5V and the motor can only support 3.5V max. You can, however, trigger a mosfet transistor with an output (called GPIO) of the Arduino. Since there is a 3.3V output on the Arduino, you will have no problem powering the motor with this:

The Mosfet will act like a switch which closes when you apply voltage to one of it’s pins.(Note: this module requires soldering)

Let me know if you need more help!
