controlling camera with rc transmitter

controlling sony block camera through 
rc remote control using arduino

for this demo i used 3.3v as power source for the
rc receiver but in real life it will probably be a 5v
power source so youll need to figure a way who to 
do it (resistors, level converter...) 

so lets start 
what you need:
sony block camera (visca)
arduino (3.3v)
rc transmitter
rc receiver
monitor with av

fcb-ex11d

arduino mini 3.3v

rc transmitter - spektrum dx6i

ar6200

then you'll need to hook up the wires as so
camera rx to arduino tx
camera tx to arduino rx
camera gnd to arduino gnd
arduino digital pin 3 to reciever elev channel


then you left with video 
and the power of the camera
power specs says 6v-12v
and video is ntsc so any suitable 
monitor will do the job



and of course the code :)
