I created a house with a light that graually turn on a light if it is dark and an alarm connected to the door the squeeze and send email if someone enter the house!
Step 1: Make the circuitUse my Fritzing file to copy the circuit I realized. You will need:
- LED
- buzz
- bulb
You can add a potenziometer (for buzz volume) and everything you'd like! Upload the casa.ino file into your board!
Step 2: Set the lightOn my file is already done!
Link a bulb lamp to a transistor and the transistor with one of your Arduino's pin. Create a circuit with a 2K resistence and a fotoresistence, this is useful to read the voltage in the connection of two resistence.
Done! The lamp turns on in the dark! I did analogRead from fotoresistence and then analogWrite to transistor!
Step 3: Set the alarmDownload Blynk app! (http://www.blynk.cc/)
Create a circuit with a push button, and a contact sensor for the door: when the door is closed digitalRead(button) should be 0! Create an email widget on the app! It's done! My code sends an email when the door's open!
