I used two 2-input OR gates to perform the operation of a 3-input OR gate.
No, it is a 2-input. I used the 74LS32 IC, which is a quadruple 2-input OR gates.

The circuit diagram is attached in this instructable (I attached it to this comment as well). Just make sure the IC chips are powered by a +5V source, and are grounded. Here is the URL for the 74LS136 IC: http://www.ti.com/lit/ds/symlink/sn74ls136.pdfHope this helps.
You might need to check the GPIO pins you are using.The provided code in this instructable uses pins number 11 & 12. Hope this helps.
