Add an easy-to-use continuous rotation input to your project, perfect for navigating through a menu, controlling volume, or connecting to a motor.

Skip adding pull-ups and debounce filters, the module includes these quality-of-life components on the underside,

Connect the module to your favourite microcontroller (ensuring you match the power supply voltage to the IO voltage).

These encoders feature the standard T18 spline and include hardware to be panel mounted like most common potentiometers. We stock a range of colourful knobs of different styles that will fit.

Check out our guide on the theory behind encoders.

Examples

Raspberry Pi Pico - Micropython

from machine import Pin
from utime import sleep

# Create pins for encoder lines and the onboard button

enc_btn = Pin(0, Pin.IN, Pin.PULL_UP)
enc_a = Pin(12, Pin.IN)
enc_b = Pin(13, Pin.IN)

count = 0

# Define a handler function for encoder line A
def encoder_a_IRQ(pin):
    global count
    if enc_a.value() == enc_b.value():
        count += 1
    else:
        count -= 1

# Initialise the interupt to fire on rising edges
enc_a.irq(trigger=Pin.IRQ_RISING, handler=encoder_a_IRQ)


while True:
    print(count)
    if enc_btn.value() == 0:
        print("Button pressed")
    sleep(1)
