Stop Signal

Simple Arduino sketch that sends a stop signal over serial whenever pin 2 is low. For use with Ephys Link.

Requirements

• Any Arduino which supports attachInterrupt on pin 2 (the specific pin can be edited later if desired)
• Serial connection between Arduino and target device
• A switch or button and appropriate wiring (anything that will close a circuit when pressed)

Installation and usage

Wiring

• Simply attach a switch or button to connect pin 2 to GND when pressed

Installation

• Install or get the latest version of the Arduino IDE
• Clone this repo (git clone https://github.com/VirtualBrainLab/stop-signal.git)
• Open StopSignal.ino
• Attach an Arduino
• Select the Arduino used and the port it is attached to through the "Tools" menu
• Upload

Usage

• When the switch is open, nothing will happen.
• Whenever the switch is closed, pin 2 will be put to LOW and a 1 (with a new line symbol) will be printed to serial.
