I want to make a R/C parachute system for my AR Drone 2.0.
Currently I have an arduino uno which has a push button on input A0 and this board sends out a serial value over a 433mhz tx from digital pin 2
I am recieving ok as watching the nano on the serial monitor
it sees the change from 0 to 1023 when I press and hold the button down for a little bit
I am very new to Arduino and have reached my current limits. So I seek your services and skills for what I would like to achieve below.
UNO- is transmitter end. I want sketch which will only transmit a character command "popchute" once a push button has been pressed, I want a LED output to go LOW when the button is pressed.
NANO- receiver end I want this to have 2 inputs as well as the recieved character command.
input 1- push switch once pressed arms parachute system and will allow output IF
input 2- is released (unpushed) (this happens once drone takes off/switch not making contact with the ground)
If command is received and inputs 1 has been armed and input 2 has gone low I want 2 output pins made high.
I hope this helps you see my vision?
