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
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 :)
