Power consumption of the embedded controller is a primary concern in low power design. Arduino boards are often used in devices that rely on battery or solar charging. Such devices often deploy far from the power line to have periodic battery replacement or are mobile devices designed for periodic charging cycles. In such a case,…
Color generation using RGB LED, Arduino, and potentiometer
RGB LED is a combination of three LEDs red-green-blue together. It has four terminals – either anode or cathode, and the other three are for these three colors. Interestingly, when two colors inside the LED are turned ON simultaneously, the LED gives a different color. Also, as the amount or intensity of any color in…
