just updated the source on github with a fix to a bug in buzzer and PWM code. I had to move the buzzer from using timer3 to timer4 so it does not conflict with digital pins 2 and 3 PWM. I currently don't use the 10v PWM.

I just ordered a jebao wp-25. It is on sale now on ebay.

I plan to make the connection from the wp-25 controller pwm to arduino analog in, and then an arduino pwm out goes to the wp-25. This way, I can just pass through the pwm signal from the wp-25 controller to the pump, but can override the pwm signal if needed. The initial implementation will just be on/off so I can turn it off during feed mode. I'll see how well the stock wp-25 controller works to determine if I need to write my own pwm routine to control the wp-25.
