This code allows to send data in json format of a DHT11 sensor to a Mosquitto MQTT broker in order to store data on InfluxDB and display it on Grafana
Non-blocking Arduino library for the DHT11, DHT21, and DHT22 sensors
Modbus library for RTU, ASCII and TCP protocols. Primarily developed on and for ESP32 MCUs.
ESP-Modbus - the officially suppported library for Modbus protocol (serial RS485 + TCP over WiFi or Ethernet).
modbus RTU client for ESP32
Publish the temperature and humidity information
Config files for my GitHub profile.
Simple library for sending measurements to an InfluxDB with a single network request. Supports ESP8266 and ESP32.
Fun little display project that includes a touch-sensitive MIDI controller. Plays virtual instruments while displaying mesmerizing animations courtesy of 250+ neopixel LEDs.
A library that allows your Arduino to communicate via Modbus protocol, acting as a slave (master in development). Supports serial (RS-232, RS-485) and IP via Ethernet (Modbus IP).
A library that allows your ESP8266 to communicate via Modbus protocol, acting as a slave (master in development). Supports IP via wireless network (Modbus IP).
Modbus Master-Slave library for Arduino
Small Modbus slave, RTU (serial) for Arduino
Very basic single button game for Adafruit Neopixels controlled by an Arduino
Arduino Pcf8563 RTC library. A fixed/expanded version of the original Rtc_Pcf8563
