How to Program an Arduino Accelerometer for Motion Controls




Introduction: How to Program an Arduino Accelerometer for Motion Controls

Motion control is always something that has peaked my interest. This is especially so recently when I found out how easy Arduino makes them to program. Once set up properly this can easily become an awesome door that opens up so many possibilities. You could for instance program an rc plane or quadcopter. You could put motors in inanimate objects and amaze your friends. As with just a few simple hand gestures you can manipulate a chair to go any way you want it. Think of all the possibilities to be motion controlled, because any thing you can plug into the arduino can now be motion controlled.

Step 1: Getting the Parts

The main parts are the arduino uno and the Gy-521 3 axis gyroscope/accelerometer or the mpu-6050

You will also need wires, soldering skills, solder, and solder iron

Step 2: Getting the Program

If you don't already have arduino's software here it is:

Here is the code I used just copy paste it to arduino's software:

Now that you have the program ready to go you have to plug in the uno to the accelerometer.

Step 3: Connecting the Two Boards

to connect the two boards first you have to solder the pins to the accelerometer. Then use the other set of pins in the box to solder to one end to each of four wires you need to cut then strip.

You then need to connect the ucc on the accelerometer to the 5v on the arduino uno board.

next connect the gnd to gnd. This should then power the accelerometer when the uno board is plugged in.

next to get information to pass from the accelerometer to the uno board you will need to connect the scl to a5 and sda to a4

Step 4: Finishing Touches

Lastly you need to run the code and then open the serial monitor. If it displays random values then you know its on and working.

Lastly something I didn't add in my video is that if you want to program it to do something with those values then you need to do a digitalwrite on whatever number you want to turn on and off. You then need to write an if else statement to have the light or whatever you decided to turn on and off respond to your accelerometers decisions.

Here is a page I found explaining digital writes:

Here is a page I found explaining if else statements:

This will be explained in greater detail and in a video with my next video on how to use this method to actually program something.

    Really awesome man!!!

    Just a question about the main Arduino Board. Will either a 5V Pro mini or a Nano also work?

    Thank you.

    Hello, for my final project I'm using an Chinese MPU 6050. I ran the code that was given but it keeps giving the same value no matter how I rotate or tilt the accelerometer.

    Any help would be appreciated!

    Hello, I am making a self balancing vehicle for my final year project using an MPU 6050, a Genuino board (might be a counterfeit), and a Cytron duo motor driver.

    However I am encountering a problem. The gyro sometimes starts giving out random absurd values and at times stops communicating. Do you think a problem with the MPU or the Arduino?

    I'd be glad if you responded with a solution

    Thank you

    On your video, about second 00:30" you show a way to connect the accelerometer that burnt my accelerometer and my board.

    Thanks a lot.

    Did you just read the dont try this it doesn't even kinda work, and then precceded to try it because its easier then legitimately wiring it up and watching the video/reading the instructable?
