# clear Counts
|
||
|
|
|
||
|
|
Set all counters for the motor back to zero.
|
||
|
|
|
||
|
|
```sig
|
||
|
|
motors.largeA.clearCounts()
|
||
|
|
```
|
||
|
|
|
||
|
|
The counters for a motor are: **tacho**, **angle**, and **speed**. Each of these counters is set to start counting from `0` again. This is a way to begin new counts without having to reset the motor.
|
||
|
|
|
||
|
|
## Example
|
||
|
|
|
||
|
|
See if the motor turns the same number of times for each of two count periods. Run the motor connected to port **A** twice for 10 seconds and compare the tacho counts.
|
||
|
|
|
||
|
|
```blocks
|
||
|
|
let tachoCount = 0;
|
||
|
|
motors.largeA.reset()
|
||
|
|
motors.largeA.setSpeed(50)
|
||
|
|
loops.pause(10000)
|
||
|
|
tachoCount = motors.largeA.tacho()
|
||
|
|
motors.largeA.clearCounts()
|
||
|
|
motors.largeA.setSpeed(50)
|
||
|
|
loops.pause(10000)
|
||
|
|
if (tachoCount == motors.largeA.tacho()) {
|
||
|
|
brick.showString("Motor turns equal.", 1)
|
||
|
|
} else {
|
||
|
|
brick.showString("Motor turns NOT equal.", 1)
|
||
|
|
}
|
||
|
|
motors.largeA.stop()
|
||
|
|
```
|
