SPECIFICATIONS

Ball Switch Sensor Module

It consists of a 10kΩ resistor and a metallic ball switch with bidirectional conduction that will open/close the circuit depending on its tilt degree. It does not measure tilt angle. Closes the circuit when it is tilted to the side as long as it is moved with enough force & degree of inclination to activate ball switch inside.

Operating Voltage: 5v DC.
This module is small and simple to use.
Digital switch output (0 & 1)
High sensitivity
Completes the circuit when the module is tilted
LED lights up when tilt switch is activated

Arduino Uno

/* The loop() function executes the program repeatedly until Specified. */

void loop ()

{

val = digitalRead (ball) ;// digital interface will be assigned a value of 3 to read val

Serial.println(val);

if (val ==HIGH) //When the tilt sensor detects a signal when the switch, LED flashes

WORKING

Welcome to the Arduino Based Project which consists of Ball switch Module and Servo Motor. The basic principle of Ball switch sensor is being described here. The ball tilt switch module can detect when it is tilted. It works because a ball flows into the gap between two electrodes and completes the circuit when the module is tilted at an angle.Here, we are controlling the rotation of Servo Motor using Ball switch. When the ball switch module is tilted, then the Servo motor rotates at 90° on either direction.
