Hi everybody, I have a idea to create a box like ''useless box'' but including my sound.So the box will use two servo and one wave shield, one servo is control the door open or close, another servo is a hand to close the switch.
I went online to find the relevant information, I find that using Arduino and Wave Shield can provide a sound. In adafruit website '' Examples | Wave Shield | Adafruit Learning System '' It provide some example to teach us how to using the wave shield and I use it to test my wave shield. The wave shield is work.
And than, I also find the servo code about useless box on GitHub and two servo are working.
When I combine the code of servo and the code of wave shield, the problem is coming out. It will have some error...
Late, I know the problem is about the ''Timer 1''. Both program are using timer1, so it will have some confuse. Some people said that using ''ServoTimer2.h'' can solve the problem but I tried so many time the result is.... I cannot solve it.
Is it have some error I missed?
Please to point out or suggest me
