Description

The H2OhNo! is a water sensor alarm kit that you build yourself. When
water is detected across the sense pins an alarm goes off and an LED
starts blinking. If you've ever had a water heater explode or tried to
create submersible electronics you know how important it is to be able
to detect when water is around!

Underneath the default function of H2OhNo! is a small but powerful
development board for the ATtiny85 microcontroller. The board includes
a buzzer, LED, a coin cell battery, and the ability to detect analog
and digital sensors. This mixture of parts creates a great low-cost
tool to learn how to program and sense things!

This board can be re-programmed to be an Annoy-A-Tron (originally made
by Think Geek). Please annoy respectfully, otherwise your board may
get demolished.

Note: Please check the hookup guide below for helpful tips and
assembly instructions.
