Fig 1. This voltage regulator circuit (a) uses green LEDs as both the stabilization elements and as the voltage indicators at the front-panel switch (b). Fig 2. The addition of resistor R4 to the ...
Using Ohm's Law to calculate the associated power resistor requirements is the basic starting point for LED thermal design. LEDs are an extremely versatile and compact alternative to the traditional ...
Layman’s RGB LED module is an ultra-simple project realized without any microcontrollers. An RGB LED can be driven with a cmos presettable up/down counter. This is accomplished by connecting the three ...
