This "nosepoke" is made to interface with an Arduino board for facilitating operant training in mice. Essentially this is a switch to trigger a digital input on the Arduino. The Arduino can be programmed to detect this switch and activate a pellet dispenser or other reward dispenser.

I made a small tweak for a colleague, giving the nosepokes slide connectors so they can be physically connected in a line. This print requires a high resolution printer, such as a resin-based printer to make use of the slide connectors. (I tried it on a PLA printer not nearly enough resolution for the slides to work well).
This is a modular design that allows for any number of nosepokes to be connected in a row like this:
Solder the photointerruper into the breakout board, and a resistor in place. The board suggests a 220Ohm resistor, we have found that up to 3KOhm works fine, and will reduce power consumption for battery-powered settings.
