Project Overview The Arduino will read the analog values from the sound sensor using the analogRead() function. These readings represent the intensity of the sound detected by the sensor. The higher the value, the louder the sound. The sensor will detect ambient noise, and higher values will appear when there are loud sounds, such as … Read more
In this project, we’ll create a simple color detection system using the TCS3200 color sensor with an Arduino. When the sensor detects a specific color, it will light up the corresponding LED — Red, Green, or Blue. The TCS3200 sensor measures the intensity of different colors by generating a frequency that corresponds to the amount … Read more
In this blog, we will walk you through how to create a simple project using an Arduino and an Ultrasonic Sensor (HC-SR04) to trigger a voice playback on an ISD1820 Voice Recording Module when a person or object comes within a specific range. The voice message is recorded manually on the ISD1820, and the Arduino … Read more
