SparkFun H2OhNo! ATtiny Dev Board Water Alarm
VariousFree shipping starting at 50.–
The H2OhNo! is a DIY water sensor alarm kit. When water is detected by the sensor pins, an alarm is triggered and an LED starts to blink. If you've ever had a water heater explode or attempted to create submersible electronics, you know how important it is to be able to detect when water is nearby!
At the core of the H2OhNo! is a small but powerful development board for the ATtiny85 microcontroller. The board includes a buzzer, an LED, a coin cell battery holder, and the ability to use both analog and digital sensors. This combination of components creates a great, cost-effective tool for learning how to program and perceive things!
This board can also be reprogrammed to become an Annoy-A-Tron (originally from Think Geek). Please annoy respectfully, or your board may be torn apart.
Note: Please read the guide below for helpful tips and assembly instructions.
