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 ...

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 ...
