i have connect on my Rfduino an piezo buzzer. But I need an continuous tone which change when i get another value from my pressure sensor.
The problem is when i start the tone function and after every cycle i hear a little crack. With an arduino uno work this perfectly without crack.
I tested with this code:
int buzzer = 3;
when i use the rfduino i need an "delay" function so that the code work. With the arduino uno i don´t need the delay function to work.
Can anybody help me??
