Potentiometer

Potentiometer (variable resistor) is similar to a regular resistor, but its resistance can be adjusted. By turning the knob, you regulate the amount of resistance.

Potentiometer(slot) -> ADC

To create Potentiometer object call Potentiometer(slot).

Also you can use short alias Pot(slot).

Since the potentiometer is analog, it can only be inserted into slots with an ADC (analog-to-digital converter), and there are only 2 such slots on the PiBody: "C" and "F".

Args:

• slot (string) - slot label ("C", "F").

Returns: Return an ADC object for the analogue pin of slot.

from pibody import Potentiometer

pot = Potentiometer("C")

---

.read() -> float

Returns value in range [0, 1.0].

pot.read()

from pibody import Pot  # short alias

pot = Pot("C")

while True:
    print("potentiometer value:", pot.read())

---

.read_u16() -> int

Read the raw ADC value in range [0, 65535].

data = pot.read_u16()
print(data)

---

.read_uv() -> int

Read the ADC value converted to microvolts.

data = pot.read_uv()
print(data)

---

.deinit()

Disable the ADC and release the pin for alternative use.

pot.deinit()
