{
i=analogRead(5);// read the voltage value of analog pin 5
if(i>512)// if larger that 512（2.5V）
{
digitalWrite(8,LOW);// turn on LED
}
else// otherwise
{
digitalWrite(8,HIGH);// turn off LED
}
}

Result
Hold the breadboard with your hand. Tilt it to a certain extent, the LED will be on.
If there is no tilt, the LED will be off.
The principle of this experiment can be applied to relay control.
Experiment completed.
Thank you!

Project 19: Magical Light Cup

Introduction
Magical light cup module is a product developed by KEYES that can interact with ARDUINO.
The principle is to use PWM to regulate light brightness of the two modules.
Mercury switch provides digital signal, triggering PWM
the designed program,
We can see effect like two cups pouring light to each other.
Hardware required
Ball tilt switch *2
Led *2
220Ω resistor *2
10KΩ resistor *2
Breadboard *1
Breadboard jumper wires *several
