Neopixel ring with 12 RGB LEDs that can be individually controlled, each of which can produce 256 shades of its color, resulting in a total of 16,777,216 colors

Overview

This is a Neopixel technology ring with 12 RGB LED diodes that can be individually controlled, each of which can produce 256 shades of its own color, resulting in a total of 16,777,216 colors. The data channel for communication is a One-Wire serial type and can be controlled with microcontrollers such as Arduino, PIC, mbed, etc. You can set the refresh frequency as desired, so as to make certain light effects imperceptible. Multiple rings can be cascaded together to create various effects. Power supply: 5 Vdc.

Your Arduino Nano ESP32 can run Doom
Your Arduino Nano ESP32 can run Doom
September 12, 2023

"But can it run Doom?" is more than just a joke in the tech world. It is also a decent litmus test for the computing power of hardware. That test isn't very relevant for modern computers, but it is still worth asking when discussing microcontrollers. Microcontrollers vary in dramatically in processing power and memory, with models to suit every application. But if you have an Arduino Nano ESP32 board, you can run Doom as Naveen Kumar has proven. The Nano ESP32 is a small IoT development board for the ESP32-S3 microcontroller, featuring Wi-Fi® and Bluetooth® connectivity. It also has a relatively high clock speed and quite a lot of memory: 240MHz and 512kB SRAM, respectively. That still isn't enough to meet the requirements of the original Doom release, which needed a lot more RAM. But Kumar demonstrates the use of an MCU-friendly port that runs well on this more limited hardware. Want to give it a try yourself? You'll need the Nano ESP32, an Adafruit 2.8" TFT LCD shield, an M5Stack joystick, a Seeed Studio Grove dual button module, a breadboard, and some jumper wires to create a simple handheld console. You'll have to compile and flash the Retro-Go firmware, which was designed specifically for running games like Doom on ESP32-based devices. You can then load the specialized WAD (Where's All the Data) files. Kumar reports an average frame rate at a 320×240 resolution, which is very playable.
