Overview Which feature of RGB LEDs has made them an attractive and practical component in Electronics and Lighting Industry?Answer: Their unique feature of regulating the ratio of the three primary colors (red, green, and blue) to generate a desired color with one LED. An RGB LED has a common pin as well as three pins for red, green, and blue colors. We can combine these primary colors to generate countless colors by controlling these pins with a PWM pulse signal. (The number of colors changes depending...

SR602 PIR Motion Detection Sensor Features PIR or Passive Infra-Red sensors detect motion based on infrared light of ambient heat. PIR sensors are commonly used in security alarms to detect the presence of human. The SR602 sensor is able to detect movement up to a distance of about 3 meters. This sensor has a digital output. When it detects motion, output will be High and it last 2.5 second. After that it returns to LOW. Note You can adjust sensitivity and HIGH time duration usin...
