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...

XKC-Y26-V Non-contact Liquid Level Sensor Features The XKC-Y26-V Non-Contact Liquid Level Sensor is a digital output sensor that detects the presence of liquid. There is an LED on the module, which will turn on if liquid is detected, otherwise it turns off. There is also a screw on the body of the module that you can use to adjust the sensitivity of the sensor. This sensor is suitable for dangerous applications such as detection of toxic substances, strong acids, strong alkalis, etc. ...

Overview Have you ever wanted to use 2 sensors with the same I2C address at the same time, not knowing what to do? Faced some serious challenges in doing that? In a lot of projects, we have used different modules and sensors that support I2C communication protocol. Sometimes, we have interfaced some I2C modules with a microcontroller in our projects. If they all have different I2C addresses, we could easily interface them, facing no serious trouble. But, if 2 or more of the modules had the same I2C address...
