 ##Info
 ###Send RC codes
 
-Use your Arduino to operate remote radio controlled devices. This will most likely work with all popular low cost power outlet sockets.
+Use your Arduino or Raspberry Pi to operate remote radio controlled devices. This will most likely work with all popular low cost power outlet sockets. If yours doesn't work, you might need to adjust the pulse length for some to work.
 
-All you need is a Arduino, a 315/433MHz AM transmitter  and one or more devices with a SC5262 / SC5272, HX2262 / HX2272, PT2262 / PT2272, EV1527, RT1527, FP1527 or HS1527 chipset. Also supports Intertechno outlets.

 ###Receive and decode RC codes
 
 Find out what codes your remote is sending. Use your remote to control your Arduino.
 
 All you need is a Arduino, a 315/433MHz AM receiver (altough there is no instruction yet, yes it is possible to hack an existing device) and a remote hand set.
