I want to make a switch that operates a pneumatic valve via an rc transmitter/receiver. The circuit also has a boost converter, so i can supply my valve with approx. 30V using a 9.9 LiFe battery.
I'm using the pulseIn command to measure the receiver pulse. I use pin 10 to control the boost converter and pin 11 is the 'switch'. It kinda works but I have a problem: when I power up the arduino it seems to briefly switch on pin 10 and 11! I really don't want that: it could potentially switch on my valve during start-up...
