## Arduino drives Angle of tilt switch ## Free shipping for SW-520D ball switch Angle of tilt switch, switch Angle sensor,tilt sensor ![Tilt angle sensor module][1] Feature 1, the use of highly sensitive angle switch SW-520D as a sensor 2, the comparator output signal clean, good waveform, driving ability, than 15mA 3, the working voltage 5V 4, the output format: Digital switching output (0 and 1) 5, a fixed bolt hole for easy installation 6, small PCB board size: 3.2cm x 1.4cm 7, using a wide voltage comparator LM393 ![Tilt angle sensor easyeda][2] Switch module output depends on the angle switch on and off, when the angle switch is turned off, DO output high, angle switch is turned on, DO output low; the output can be directly connected to the arduino MEGA 2560 through the arduino MEGA 2560 to detect high and low, thereby detecting the angle change. relay outputs can directly drive module, which can be composed of a high-power switching angle, protection of electrical equipment and other products dumped automatic power-off function. **arduino CODE** void setup() { pinMode(13,OUTPUT); } void loop() { int i; while(1) { i=analogRead(5); if(i>200) { digitalWrite(13,LOW); } else { digitalWrite(13,HIGH.); } } } [1]: /editor/20151218/5674064594ed5.jpg [2]: /editor/20151218/567407cc584ce.JPG
