This was designed with KiCAD so I think I need to upload these files: *.pro, *.sch, *.kicad_pcb .&lt;br /&gt;
I have a bunch of Gerbers as well but they are not *.GBR .&lt;br /&gt;
Happy to upload but not sure what format is best.&lt;/div&gt;</summary>

&lt;br /&gt;
A circuit board for sensing nosepokes, delivering water, and providing feedback with an LED -- remixed for a single poke!&lt;br /&gt;
&lt;br /&gt;
This printed circuit board (PCB) connects to the back of a nosepoke and provides passive circuitry and connectors to enable poke sensing, solenoid activation (by digital trigger or by a pushbutton switch), and tricolor LED triggering.&lt;br /&gt;
&lt;br /&gt;
The following connections are needed with the raspberry pi, from top to bottom:&lt;br /&gt;
1. 5V&lt;br /&gt;
2. LED4 (blue); a digital trigger&lt;br /&gt;
3. LED3 (green); a digital trigger&lt;br /&gt;
4. LED1 (red); a digital trigger&lt;br /&gt;
5. Solenoid; a digital trigger&lt;br /&gt;
6. Nosepoke detector; a digital signal indicating poke&lt;br /&gt;
7. 3V3&lt;br /&gt;
8. Gnd&lt;br /&gt;
&lt;br /&gt;
You have to insert resistors, BJTs, a diode, a solenoid valve, the beam-break sensor, and the solenoid into the marked locations on the PCB. A guide demonstrating this with pictures is coming. :)&lt;br /&gt;
&lt;br /&gt;
The LED and solenoid digital triggers activate their respective devices when the signal from the raspberry pi goes HIGH (3.3V, not 5V). This is done by opening a BJT, so that those devices draw their power from the 5V rail, not directly from the digital pin on the raspberry pi. Resistors should be inserted in the indicated location between these digital signals and the BJTs.&lt;br /&gt;
&lt;br /&gt;
A single current limiting resistor (R_LED) controls the current flow through the LEDs. Only one LED should be activated at a time.&lt;br /&gt;
&lt;br /&gt;
A diode blocks kickback current from the (inductive) solenoid valve, as recommended on the solenoid's datasheet.&lt;br /&gt;
&lt;br /&gt;
You can order this PCB directly from OSH Park for $20.30 for a batch of three at this URL: https://oshpark.com/shared_projects/uUbjkQ0y&lt;br /&gt;
I don't receive any financial benefit from any orders you make.&lt;br /&gt;
&lt;br /&gt;
I can also send you the KiCAD design files and you can edit it or print it however you see fit.&lt;br /&gt;

This is an alternative to the OPB901L55. The form factor and pinout are identical. However, the output is inverted: high normally and low during the poke. Flip the POLARITY setting in prefs.json to make this work.&lt;/div&gt;</summary>
