so i managed to transmit a box wave from an a434 transmitter with it's data connected to a shmidtt trigger oscilator composed of a 74ls14 ic, a 1uf capacitor and a 1k resistor with a 1k pot. the problem is i have no idea how to make the arduino detect that. what i would need is something that counts the frequency every 100 ms or so it can choose which servo (there's one on each side) moves faster. i can do the servo selection but what i don't know is the syntax for reading a frequency. it's a square wave that gets transmitted so that's what i'd need . admittedly i was tainted by BASIC before moving to the arduino.
