And what happens when you run that sketch?heres my code for the 1st sketch
Code: Select all
v2 = v2 - 40;
Thanks for the reply but it seems to just pull the motor and keep straining but not return to position.adafruit_support_bill wrote:Ok then, choose a higher number for a faster decay on V2. You can adjust this number to tune the movement.
Code: Select all
v2 = v2 - 40;
But the Servo library doesn't work with the WaveHC library due to the timer conflict. You can try the Software servo link i posted earlier. I have never used that library, so I don't know how well it works.would it not be better to work out a way of incorperating the wave shield in my sketch with the servo? as its the perfect movement i need.
You have to install the library in the location where the compiler expects to find it. See this guide for details on how to install a library.but each one just comes up as "does not name a type" ?
