+# Teensy 2.0 splittest
+
+To trigger keypress, short together pins *F5* and *F7*
+
+## Wiring
+- Add switches to both Teensy 2s across F5 and F7 pins
+- Add pull-up resistor to left side between VCC and F0
+- Add pull-down resistors to right side between GND and F0
+- Connect the following pins on both sides together: D0, D1, GND, VCC
+- Add I2C 4.7kOhm resistors between D0 and VCC, and D1 and VCC
+- Wire Di of RGB strip for each half to D3
