Measure voltage of analog input pin
Measure the voltage of an analog pin relative to the analog input reference voltage on the Arduino hardware. Output the measurement as a 10-bit value that ranges from 0 to 1023.
If the measured voltage equals the ground voltage, the block output emits 0.
If the measured voltage equals the analog reference voltage, the block output emits 1023.
The default value of the analog input reference voltage is 0 to 5 V. To change the Analog input reference voltage parameter in your model Configuration Parameters, select Tools > Run on Target Hardware > Options.
During simulations without the hardware, this block emits zeroes. See Block Produces Zeros or Does Nothing in Simulation
Enter the number of the analog input pin.
Do not assign the same pin number to multiple blocks within the model.
If you set the Target hardware parameter to:
Arduino Mega 2560, enter a pin number from 0 to 15.
Arduino Uno, enter a pin number from 0 to 5.
Arduino Nano, enter a pin number from 0 to 5.
Arduino Due, enter a pin number from 0 to 11.
Specify how often this block measures the voltage of the analog input pin, in seconds. Enter a value greater than zero. This value defaults to a sample time of 1 second. The minimum value is 0.000001 second.
Smaller values require the processor to complete the same number of instructions in less time, which can cause task overruns.
