  • MAX7219 Dot Led Matrix Module MCU LED Display Control Module Kit For arduino ()
    MAX7219 is an integrated serial input / output common-cathode display drivers , which connects the microprocessor 7-segment digital LED display with 8 digits , bar graph can also be connected monitor or 64 separate LED. On type B BCD encoder includes an on-chip , multi-channel scanning loop , segment word drive, but also a 8x8 static RAM for storing each data . Only one external register is used to set the segment current for each LED .
     
       A convenient four-wire serial interface can connect all common microprocessor. Each data can be addressed in the update does not overwrite all of the display . MAX7219 also allows the user to select each of the data code or not coded .
     
       The entire device includes a 150μA low-power shutdown mode , analog and digital brightness control , a scan-limit register allows the user to 1-8 bits of data , there is an LED light so that all the detection mode .
     
       Requires only three IO ports can drive a dot ! No flashing dot matrix display ! Support cascade !

    Single module can drive a common cathode 8 * 8 dot matrix
     
       Module Operating voltage : 5V
     
       Module size : 5 cm X 3.2 cm wide X 1.5 cm high
     
       Holes with four screws , diameter 3mm, can be fixed by using our M3 studs
     
       Mdules with input and output interfaces , support for cascading multiple modules

  • Red LED's 3mm ()
    Need some indicators? We are big fans of these diffused red LEDs, as featured in the LoL shield. They are fairly bright so they can be seen in daytime, and from any angle. They go easily into a breadboard and will add that extra zing to your project.

  • Red LED's 5mm ()

     LEDs - those blinky things. A must have for power indication, pin status, opto-electronic sensors, and fun blinky displays.

    This is a very basic 5mm LED with a red lens. It has a typical forward voltage of 2.0V and a rated forward current of 20mA.

  • Adafruit 16x24 LED MATRIX ()
    These LED panels take care of all the work of making a big matrix display. Each panel has six 8x8 red matrix modules, for a 16x24 matrix. The panel has a HT1632C chip on the back with does all the multiplexing work for you and has a 3-pin SPI-like serial interface to talk to it and set LEDs on or off (you cannot set the LED to be individually dimmed, as in 'grayscale'). There's a few extras as well, such as being able to change the brightness of the entire display, or blink the entire display at 1 Hz.

    One really nice thing about this particular LED matrix module is that it is designed to be 'chainable' - you can connect to 8 panels together to make an extra long display.
