Fairly certain that Arduino is not interpreted, it is compiled. The Arduino language may be interpreted to C/C++, but then it is compiled. There is not an interpreter program running on the Arduino.
I do agree that Arduino is a better option than learning C/C++ and programming a PIC. The...
The driving force in a circuit breaker is the current, especially if it's using a solenoid to trip at the rated current. Therefore, whether you're running 120V or 240V through it doesn't matter, it will always trip once it hits 20A.
It's a crummy picture, but this is a picture of the secondary right after racking:
Here's your hint: I don't dry hop using bags.
It's a clone recipe of a beer that is listed in the BJCP guide as a commercial example of the style. Bonus points if you can guess what I was trying to clone...
If the motor is synchronous then you'll have trouble operating at a lower voltage as yjfun has said. However, if it's an induction motor then you're safe operating at a lower voltage, it will just operate at a lower speed and deliver less power. I looked around briefly, but I couldn't find a...
