Remote control 4WD robot build part1

A couple of parcels of parts arrived last week and I have started assembling my next robot project (possibly for code club). It’s a 4WD drive robot with an nRF24L01+ based remote control.

Had a slight problem with pin usage, the Embedded Coolness nRF24L01 shield and Pololu Dual MC33926 Motor Shield both use pin D2(irq) & D7(csn). The polulu shield supports some customising of pins so I disconnected D2(Status flag indicator), cut the D7 link (Motor 1 direction input) and wired it to pin D5.

I’m using the nRF24l01 driver from codeplex as basis for both ends of my remote control, code to follow…
