808 Keycam recording with Remote control
i want using my keycam with the remote controler.
for that i want using the channel from the original vga camera from my copter.
i have 3 wires for that:
red/black give 5v power(ideal for the keycam)
red/white has constant power of 0v and give short pulse of 3.3v if i press button on remote control.
black/white has constant power of 3.3v and give short pulse of 0v if i press button on remote control.
so i looked on the picture of the board from here:
I just connected the wires for the "record" button, pressthe key on the remote and nothing happend.
do i ave a logic error in my planings ?
i thought if the 3.3v pulse from the remote came to the "record" button the same happend as i press the button manualy.
excuse my bad english and i hope i find some help here
is there a way to use the short 3.3v pulse to control the lights on/off ?
lets say theres a component getting the 3.3v pulse and open a circuit to get power for the led's.
on next pulse he close the circuit to power off led's
