Universal Arduino Controller

A few weeks after school got out I built a small Arduino robot. I wanted to move to the next step and I needed a controller. I started looking for a controller that let me choose what kind of signal to use but was unsuccessful. So I made my own. I own a NRF24L01+ module which is what I am going to use to control this robot but there is a place for a Bluetooth piece to attach. I cut space in the model to help make the NRF chip fit better and I may need to make similar changed to make room for Bluetooth modules
