We have two measurements of the angle from two different sources. The measurement from accelerometer gets affected by sudden horizontal movements and the measurement from gyroscope gradually drifts away from actual value. In other words, the accelerometer reading gets affected by short duration signals ...
Serial.println ("Gyroscope"); } void loop () { endtime = micros(); // End time for the current Measurement if (firstcall) { firstcall=false; } else { dt = (float)(endtime - starttime)/1000000; // Get time beetween measurements gyro_rateX=gyro.readX_DegPerSec(); // Current ...
Inertial Measurement Unit (IMU) Essentially IMU is used to calculate the angle between the quadcopters each axis and the ground. Normally IMU used inside quadcopters must have at least two elements - an accelerometer and a gyroscope. Not going too much into the details on how IMUs are made...
• It also supports 6 analog pins which reads voltage and not current. Inside, it converts analog measurement to digital for various purposes. It supports digital pins (0 to 13) which can function either as input or output. • It has various interfaces viz. I2C, digital pins, analog p...
Applying this, we will use the gyroscope of the phone to control the angle of a servomotor. Chapter 7, Voice-activated Arduino, teaches us how to use the powerful Android speech API to control an Arduino board via Bluetooth. Chapter 8, Control an Arduino Board via NFC, shows how to use...
So, we can either use the ADXL345 accelerometer in combination some gyroscope sensor, or use theMPU6050 IMU which has both 3-Axis accelerometer and 3-Axis gyroscope integrated on a single chip. You can find more detailed tutorial on this sensor in my next video. ...

Inertial measurement unit (IMU) modules like the GY-87 combine many sensors into a single package, such as the MPU6050 accelerometer/gyroscope, the HMC5883L magnetometer, and the BMP085 barometric pressure sensor. Hence, the GY-87 IMU MPU6050 is an all-in-one 9-axis motion tracking module ...
We can operate the device with just a single button. Once we power the device we need to select the unit of measurement. By pressing the button we can toggle through the units, and if we press and hold the button for a while we will get into the first program. Here we can measure ...
Newer v1.2 and v1.3 boards also have a 3-axis gyroscope on the same I²C bus. The specific inertial sensor chips used on a shield depend on its version: The v1.3 version uses an LSM6DS33 accelerometer and gyro and an LIS3MDL magnetometer. LSM6DS33 datasheet (1MB pdf) LIS3MDL ...
