A month ago I described my prototype coin door volume control using a rotary encoder. I am now proud to announce a rotary encoder product with the following features:
- Positive feedback of clockwise or counter-clockwise movement via detents. There are twenty detents for a complete revolution. Under Windows 10 each detent changes the volume by 2% so it takes at most two and half revolutions to go from 0% to 100% volume.
- Sends an active low pulse for a clockwise (up) or a counter-clockwise (down) rotation on one of two wires.
- Monitor LED provides feedback by flashing for each pulse on the up/down wires.
- Knurled, black aluminum knob for precise grip and classic finish. This knob is good quality and has some heft which contributes to the feel of the control.
- Integrated pushbutton provides a third input that can be used for mute or any other kind of function.
- Powered from standard 5V but is 3.3V input compatible (e.g. for KL25Z).
- Keyed and locking 5-pin connector for power and 3 inputs which eliminates accidental disconnection if the cabinet is moved or the coin door is opened.
- Integrated microcontroller translates rotary encoder clockwise and counter-clockwise movement into active low pulses to simulate a button press for a keyboard controller. Nothing extra needed except wiring to 5V power and an input controller such as Pinscape or LED-WIZ.
While the original motivation for the Rotary Encoder board was a volume control for a virtual pinball coin door, the three inputs can be used to control anything; only limited by the imagination of the customer.
The cost of Oak Micros Rotary Encoder is
$12 $15 not including first class shipping to the US and rest of the world. The package includes the encoder, circuit board, knob, cable, and 10 additional crimp pins as shown below:
