The Arduino UNO R4 WiFi has a vibrant 12x8 LED matrix for creating visual patterns, animations, and more. To help you design and implement custom patterns for the LED matrix, we’ve developed a tool that simplifies the process.

Dot matrix displays are a staple in microcontroller projects, offering a versatile way to showcase custom graphics, animations, and messages. Whether you're working with an Arduino, Raspberry Pi, ESP32, ESP8266, or STM32, creating dot matrix glyphs no longer needs to be a time-consuming task. This article introduces an intuitive tool …

This CAN Bus calculator will help you calculate the configuration values given the desired bit rate and system clock frequency.

This calculator will help you compute the desired PWM frequency. Just put in the clock frequency and the desired PWM frequency and click the "calculate" button. The prescaler value and the ARR (auto-reload register value) will be the results.

This calculator will help you compute the required PSC and ARR values to achieve your desired timer interrupt period. Just put in the timer interrupt period, the clock frequency, and the ARR register width.

This guide shows the GPIO pins, ADC channels, power pins, boot pins, communication pins, and safe-to-use pins on the ESP32-WROOM-32 development board. Use the diagram and tables below to choose the right pins for sensors, I2C, SPI, UART, PWM, touch input, and analog readings. The guide shows the 30-pin and …
