kriszrap:
You work ring pin with ardunio??XY pin INPUT mode and HIGH és nothing....
void setup() {
pinMode(12,INPUT); //ring
}
void loop() {
digitalWrite(12, HIGH);
}
Hi!
I think good idea is to use the optocoupler (for example) to shortcut sleeve with ring for shift.
Did you connect sleeve to ground?
How did you calculate the cutoff frequences?
Could you please post your working code?
Thank you!
