| + | **Function Introduction** | ||
| + | |||
| + | analogRead() | ||
| + | Description: Read the value of the specified analog pin. | ||
| + | |||
| + | Function prototype: analogRead(pin) | ||
| + | |||
| + | Parameter: Analog input pin | ||
| + | |||
| + | Return value: an integer between 0 to 1024 | ||
| + | |||
| + | map() | ||
| + | Description: Map data from one range to another. | ||
| + | |||
| + | Function prototype: map(value, fromLow, fromHigh, toLow, toHigh) | ||
| + | |||
| + | parameter: | ||
| + | |||
| + | value: The data to be mapped. | ||
| + | |||
| + | fromLow: The lower limit of the current range. | ||
| + | |||
| + | formHigh: The upper limit of the current range. | ||
| + | |||
| + | toLow: The lower limit of the target range. | ||
| + | |||
| + | toHigh: The upper limit of the target range. | ||
| + | |||
| + | Return value: Remapped data | ||
| + | |||
| + | **Experimental Analysis** | ||
| + | |||
| + | The program uses the analogRead() function to read the analog input value, and the input value range is between 0 to 1024. Then use the analogWrite() function to change the LED light duty cycle, and the duty cycle range is 0 to 255. Remap the range by using the map() function. | ||
