Controller

A 7x Button Controller with 8x LED ring

---

Overview

Controller is a 7-button DUELink microcomputer with an 8-LED ring for status indication. Use it as a self-contained input board or as a controller layer for other DUELink modules over its Downlink port.

Code it in Python, JavaScript, .NET, Arduino, or C++, or run it standalone with MicroBlocks.

Pick Controller for handheld controls, prop interfaces, makerspace check-out stations, or any project where you want a tactile button panel with built-in feedback.

Key features • 7x buttons • 8x LEDs • USB Type C • 71x37mm Overall Dimension

🌿 Cables not included

Modules ship without cables to reduce waste. Some specialty boards include a USB cable; for the rest, see Cables to add cables to your order.

Commands

Commands this module accepts. See Samples for runnable code in popular host languages.

Function	Description
BtnPin(p)	Returns pin number, based on p value ('U' = Up, 'D' = Down, 'L' = Left, 'R' = Right, 'A' = A, 'B' = B).
Setled(l,v)	Sets Led at l (1 to 8) to a v value (1 on, 0 off).
SetAllLed(v)	Sets all Leds to v value (1 on, 0 off).
DVer()	This driver version.

Peek under the hood

The script below is this module's driver — it teaches the hardware how to respond to the commands listed above. It ships pre-loaded from the factory; most users never need to open it.
