Our project is infact an Arduino with Serially Interfaced MAX7219 Operates an 8X8 LED Matrix to display a heart pattern. The MAX7219 IC is a serial input/output common-cathode display driver that ...

The Arduino then controls the state of the LED using the active high enable line from the column multiplexer chip. [Alex] wanted more than just a static image to show off on his new display, so he ...

You can control the brightness of these LEDs using variable resistors VR1, VR2 and VR3 respectively. Parts Needed. Arduino UNO board – 1 ; 5mm LEDs Red, Green, Blue – each 1 ; 100K Variable resistor – ...

Here’s a cool hack to get you in the December holiday mood! Arduino controlled Christmas lights! It all started because [Anx2k] had some leftover LED’s from one of his other projects, s… ...

Designed to specifically make debugging Arduino projects easier and quicker the DeDe is capable of providing quick feedback on the logic state of any GPIO pin with bright red and green LEDs, even ...
