In this tutorial, I will guide you step by step on how to create and fabricate a 5x5x5 LED cube using Arduino Mega. This tutorial will also cover all the fundamentals required to make a 5x5x5 LED cube, like how to create a 3D arrangement using LEDs, how to create different animations and patterns, working of the circuit and code, board and pin configuration of Arduino Mega. Board configuration of Arduino Mega Pin Configuration of Arduino Mega Digital I/O Pin: D0-D53 Analog Input Pins: A0-A15 PWM Pins: 2 – 13, 44 – 46 I2C pins: SDA(20), SCL(21) SPI pins: 50 (MISO), 51 (MOSI), 52 (SCK), 53 (SS) UART Pins: TX0-D0, RX0- D1 TX1-D19, RX1- D18 TX2-D16, RX2-D17 TX3-D14, RX3-D15 Features of Arduino Mega Operating Voltage: 5V Input Voltage: 6-20V Operating Current: Output Voltage: 3.3V and 5V Output Current: 20mA(5V) and 50mA(3.3V) Digital I/O pins: 54 ADC pins: 16 PWM pins: 15…
