However, if I also want to light up the bottom right corner in the front (3,3,0), I run into problems. If i only want to light up one led at a time, or only light up more than one layer at the same time.

Now if i want to light up the LED in the upper left corner in the back (0,0,3), I just supply GND (-) to the upper layer, and VCC (+) to the column in the left corner. All the LEDs on a horizontal layer share a common cathode (-). All the LEDs aligned in a vertical column share a common anode (+). One way to get around this, is to split the cube into 4 layers of 16x16 LEDs. How to control 64 LEDs without using 64 individual wires? Running a wire to the anode of each led would obviously be impractical, and would look really bad. 4x NPN transistor BC338 (or other transistor capable of switching 250-ish mA).Know how to program an AVR microcontroller - I will not cover that in this instructable.Basic electronics and soldering skills.The pins D0 to D7 contain data that is to be passed and D8 to D11 pins contain the address of the register.First of all, you need quite a bit of time to solder together 64 leds ) Knowledge list:

Data is sent out at the serial output pin on the falling edge of CLK. Then this data is passed to either the digit or control registers on the rising edge of LOAD/CS. On the rising edge of a clock input, this data is shifted into the 16-bit shift register integrated inside this chip. How to use MAX7219?Ī 16-bit data is sent at serial DIN input. One of the biggest advantages of using this IC is you can address Individual digits without rewriting the entire display.

16×2 LCD Module – Liquid Crystal Displayĭue to its compact structure and four-wire serial interface, it can be connected to all common microprocessors (µPs), 7-segment LED displays, bar-graph displays, or 64 individual LEDs.

The maximum current for each segment pin is 100mA and for each DIGIT ground pin is 500mA.

MAX7219 works well in a temperature range of 0☌ to +70☌.

The data is displayed on segments with a delay time of 2.2ms.

It provides a feature of digital and analog brightness intensity control and a 150♚ shutdown mode in which the current of all segments is pulled to ground.

Normally, the voltage supply of +5V is used. Its operation is specified in a voltage range of +4.0 to +5.5V.It is an LED driver display IC with a 10MHz serial interface which allows the user to select the decode/No-Decode digit.It is the terminal for a positive power supply.
