Light Emitting Elements And Their Types

Light Emitting Elements and Their Types INTRODUCTION The use and application of light cannot be overemphasized. Our natural source of light being an electromagnetic radiation that reaches us from the sun. Without that radiation, no life would remain on this planet. The ultraviolet ray reaching us from the sun is trapped by the green plants. They make use of it …

Arduino PWM Programming and its functions in Arduino

PWM function in Arduino. Arduino Programming of PWM

Arduino PWM Programming and its functions in Arduino What is PWM? PWM stands for “Pulse Width Modulation”. This technique is widely used in almost all devices in which voltage variation is required. In PWM, steady DC Voltage is converted into square wave with varying pulse width and the ratio of the total time period (T) of the wave to the …
