Surface-mount array takes on medium-power lighting LEDs

Cree has introduced a multi-die 500 lm (80CRI, 3,000K) surface-mount lighting LED, aiming to compete against multiple single-die medium-power LEDs in automated luminaire manufacture. The idea is analogous to the way bolt-down multi-die chip-on-board modules (CoBs) are taking-on single-die LED boards in manual assembly lighting manufacture. Named MH-B, the new LED “combines the reliability and manufacturabil ...

How to use an array with Arduino

This variation on the For Loop example shows how to use an array. An array is a variable with multiple parts. If you think of a variable as a cup that holds values, you might think of an array as an ice cube tray. It's like a series of linked cups, all of which can hold the same maximum value. The For Loop example shows you how to light up a series of LEDs attached to pins 2 through 7 of the Arduino, with c ...
