# Calibrate Gyro

|
|

|
|
## Introduction @fullscreen
|
||
|
|
|
||
|
|
The gyroscope is a very useful sensor in the EV3 system. It detects the rotation rate
|
||
|
|
which can be very useful to correct the trajectory of the robot and do precise turns.
|
||
|
|
|
||
|
|
However, the sensor can be imprecise and subject to drifting. It is recommend to
|
||
|
|
calibrate your sensor at least once after starting your brick. You don't have to
|
||
|
|
recalibrate on every run.

## Step 1 Show ports
|
||
|
|
|
||
|
|
Add the ``||brick:show ports||`` to see the status of the gyroscope.
|
||
|
|
|
||
|
|
```blocks
|
||
|
|
brick.showPorts()
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
## Step 2 Calibration
|
||
|
|
|
||
|
|
Add a ``||sensors:calibrate gyro||`` block to calibrate the gyro. The block
|
||
|
|
detects if the sensor is present and does a full reset of the sensor if necessary.
|
||
|
|
|
||
|
|
```blocks
|
||
|
|
brick.showPorts()
|
||
|
|
sensors.gyro2.calibrate()
|
||
|
|
```
