Firmata Analog Output Channel¶
Description¶
Analog output channel on a Firmata Device.
Note: Most Firmata-compatible devices do not support true analog output. Instead, they simulate it using pulse-width modulation (PWM). Therefore, the actual output voltage will cycle between the minimum and maximum voltages supported by the device, producing a time-average voltage that approximates the desired value.
Signature¶
iochannel/firmata_analog_output
Required Parameters¶
pin_number¶
- Example
3
Output pin number
value¶
Variable from which to read output values. The value must be between 0 and 1 (inclusive) and indicates the fraction of the device’s operating voltage (typically 5V or 3.3V) to output on the specified pin.
