Here we need to activate the sensor or enable the measurement, by sending appropriate bye to the power control register and here’s.
#Arduino gyroscope serial#
We need to initiate the wire library and start the serial communication, as we will use the serial monitor for showing the results. We will start with the accelerometer first, we need to include the arduino wire library and define the registers addresses of the sensor in the setup section.
#Arduino gyroscope code#
Ok, now let’s see the code for getting the data from the sensors. You can check my I square C communication tutorial.

These addresses can be found from the datasheet of the sensor and I have attached links to each of them on my website for more details, how this communication works. So, in order to make the communication between the Arduino and the sensors, we need to know their unique device addresses and their internal register addresses for getting the data out of them. This board used the I Square C communication protocol, which means that we can use all the sensors with just 2 wires. As an example, I will use the G Yad, breakout board, which has the following: sensors: a DXL 345 Q, axis accelerometer, LG, g4, 200 D, 3 axis gyroscope, MC 588, 3, L, 3, axis magnetometer, and also a barometer and a thermometer which we won’t use in this Tutorial first let’s hook up the board to the Arduino. Okay, now let’s connect these scissors to the Arduino board and make some use of them.

So when these materials are exposed to magnetic field, they change their resistance. These sensors use materials that are sensitive to magnetic field, usually composed of iron and nickel. The other ten percents of the sensors on the market use the magnet or resistive effect. This means that if we put a mirror now between these two sides, we will get some voltage, which depends from the magnetic field, strength and its direction. Now, if we bring some magnetic field near the play, we will disturb the straight flow and the electrons will deflect to one side of the plate and positive poles to the other side of the plate. If we have a conductive plate like this, and we set current to flow to it, the electrons would flow straight from one to the other side of the plate. It measures the earth magnetic field by using Hall FA or magnet or resistive effect.Īctually, almost 90 percent of the sensors on the market use the Hall effect and here’s how it works. Okay, now let’s explain how the magnetometer works. The microstructure of the gyroscope looks something like this: a mass that is constantly moving or oscillating and when an external angular rate will be applied, a flexible part of the mass would move and make the perpendicular displacement. This displacement will cause change in capacitance, which will be measured process and it will correspond to a particular angular rate. Next is the gyroscope which measures angular rate using the Coriolis effect when a mass is moving in a particular direction, with a particular velocity and when an external angular rate will be applied, as shown with the green arrow, a force will occur, as shown with the blue Arrow, which will cause perpendicular displacement of the mass so similar to the accelerometer. This change in capacitance will be measured process and it will correspond to a particular acceleration value. So when an acceleration in the particular direction will be applied, the mass will move and the capacitance between the plates and the mass will change. Its microstructure looks something like this: it has a mass attached to a screen which is confined to move along one direction and fixed outer plates. We will start with the accelerometer it measures acceleration by measuring change in capacitance. Also with the processing development environment, we will make some practical applications using the sensors first let’s briefly explain how each of these micro, electromechanical systems or MEMS sensor work.
