Some general precautions for your Arduino:
- Don't under/over power your Arduino
- Don't pull more than 40 mA on most boards from one digital pin
- Don't apply more than 5V to any pin (except VIN)
- Don't change a circuit while the Arduino is powered
Some general precautions for you/the people around you:
- Don't apply mains to your Arduino.
- When powering high voltages with a relay, make sure to cover and seal any wires that might be connected to the high voltages.
- Arduino not to be used as a flotation device. Really, don't get your Arduino or any other part of your setup wet.
