The backlighting system of MacBook Pro keyboards could be upgraded to include TrueTone capabilities, with Apple examining the use of multiple LEDs per key to make the light seem even despite changes ...
This simple circuit allows us to drive serially connected seven LEDs by using a single NiMH (Nickel Metal Hydride) AA cell. As you can see there are a few components, a CMOS 555 timer, an NPN ...
The traditional way to control the output of multiple LEDs is to dedicate a pulse width modulation (PWM) controller to each LED and use the controller to transform the input voltage to a current that ...
LEDs are a wonderful technology. You put in a little bit of power, and you get out a wonderful amount of light. They’re efficient, cheap, and plentiful. We use them for so much! What you might not ...
High power LED lighting is harder than it looks. Power, dimming, control, and communication collide in one design.
