WizFi360/ESP8266/ESP32 wrapper library for Arduino providing an easy-to-use way to manipulate ESP8266/ESP32-AT shields.

This library enables you to use Interrupt from Hardware Timers on an nRF52-based board. These nRF52 Hardware Timers, using Interrupt, still work even if other functions are blocking. Moreover, they are much more precise than other software timers using millis() or micros(). Now supports `Sparkfun Pro nRF52840 Mini`

Code snippets and examples for NRF52832 based Arduino board

A split (semi-)wireless keyboard with ZMK support based on the NRF52832

This library enables you to use Hardware-based PWM channels on nRF52-based boards to create and output PWM to pins. Using the same functions as other FastPWM libraries to enable you to port PWM code easily between platforms.

Simple WiFiManager for Blynk with MultiWiFi Credentials, for Mega, SAM DUE, SAMD21, SAMD51, nRF52, STM32, RP2040-based, etc. boards running ESP8266 AT shields. Configuration data saved in EEPROM, SAMD EEPROM-emulated FlashStorage, SAM-DUE DueFlashStorage or nRF52/RP2040 LittleFS

Repository for the Code driving my RGB Wrench Mask

Arduino library to enable simple access to hardware-based true random number generators. API surface is stable, currently only supporting nrf52 chipsets, but easy to expand to ESP32 or others. If adding a platform is of interest, submit a PR.

u-blox NINA-B1 Arduino example + SHT31 temperature and humidity + Bluetooth BLE

This library enables you to use 1 Hardware PWM module on nRF52832/nRF52840-based board, such as AdaFruit Feather nRF52832, nRF52840 Express, Itsy-Bitsy nRF52840 Express, etc. to control up to 16 or more servo motors.
