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 :)
