Takes the outputs of 2 2 pole tilt switches and displays their current state(s) on 4 LEDs. Each tilt switch covers 2 cardinal directions, and is named as such in the code. In other words, one switch ...

In the Arduino IDE, by using digitalRead() with the pin connected to the tilt switch, you will get either a HIGH or LOW (1 or 0) signal. ... You will also need to configure which pins you are using ...

The type SW-520D is a commonly available roller-ball type tilt sensor consists of two conductive elements (poles) and a conductive free mass (rolling ball), encapsulated in the same case. When the ...

LED is connected with the PIN 2 of the Arduino UNO with 220-ohm resistor to limit the current to a safe value. And, the buzzer is directly connected to the PIN 3 of the Arduino UNO. Tilt Sensor . This ...
