Abstract

This project required the usage of an Arduino UNO and an ultrasonic sensor to complete a task. To follow this requirement a proximity LED dimmer and alarm were designed using a c++ code and circuit building techniques. This device works by sending out a high frequency sound and recording the time it took to return to the ultrasonic sensor. This time is used to find how far away an object is from the ultrasonic sensor, using the calculated distance the device decides what it will output. If the object is greater than 10 cm away the alarm does not sound and the lights brightness is scaled, the alarm will go off and the light will turn off if the object is within 10 cm of the sensor.
