Each Bar absorbs approximately 60-65mA at 12V. Here three such LED light bars (one Red, one Green and one blue) are used to complete the circuit. Use a standard 9V battery to power the arduino board, ...

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 ...

Discrete LEDs make great output devices, but LED bar graph & 7-segment displays take things up a notch. ... Assuming we’re using the Arduino Uno with its 5 V supply, this meant I would calculate the ...
