Access control systems within a building may be linked or standardized based on the size of the organization and the varying levels of security. It is suitable for homes, offices and other access control applications. Access control systems were typically administered in a central location. Besides ...
The frequency counter uses IC 555 timer to provide clock signals at a precise time interval of one second. Arduino UNO is used as a square wave generator. AnIC 555 timerand square wave generator can be configured as anastable multivibrator. The 16×2 LCD display is used to display the freq...
[25] integrated the SW420 vibration sensor with the Arduino UNO to detect the presence of a train. The vibrations on the rails induced by the incoming train can be sensed by the MEMS sensors and the vibration output is displayed on the liquid-crystal display (LCD). A similar sensor is ...
