NodeMCU started on 13 Oct 2014, when Hong committed the first file of nodemcu-firmware to GitHub. [13] Two months later, the project expanded to include an open-hardware platform when developer Huang R committed the gerber file of an ESP8266 board, named devkit v0.9. [ 14 ]
Open Compute Project, an organization for sharing designs of data center products among companies; Open Graphics Project, a project that aims to design a standard open architecture for graphics cards; OpenCores, a loose community of designers that supports open-source cores (logic designs) for CPUs, peripherals and other devices.
This is commonly done using the Servo library in Arduino. To sweep a servo with an Arduino, connect the servo's VCC (red wire) to 5V, GND (black/brown) to GND, and signal (yellow/white) to a PWM-capable pin (e.g., Pin 9). Use the Servo library to control movement. The code below gradually moves the servo from 0° to 180° and back in a loop.
SparkFun ESP8266 Thing. The reason for the popularity of many of these boards over the earlier ESP-xx modules is the inclusion of an on-board USB-to-UART bridge (like the Silicon Labs' CP2102 or the WCH CH340G) and a Micro-USB connector, coupled with a 3.3-volt regulator to provide both power to the board and connectivity to the host (software development) computer – commonly referred to as ...
Gadgeteer sets out rules about how hardware devices packaged as add-on modules may connect to the mainboard, using solderless push-on connectors. Gadgeteer includes a small class library to simplify the implementation details for integrating these add-on modules into a system. It is a way of assigning the plethora of functions that a ...
ESP32 is a series of low-cost, low-power system-on-chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth.The ESP32 series employs either a Tensilica Xtensa LX6 microprocessor in both dual-core and single-core variations, an Xtensa LX7 dual-core microprocessor, or a single-core RISC-V microprocessor and includes built-in antenna switches, RF balun, power amplifier, low-noise ...
Project experts, intermediate developers, and beginners from around the world share ideas, knowledge and their collective experience as a project community. Wiring makes it easy to create software for controlling devices attached to the electronics board to create various interactive devices.
The project was started as a Python application by Paulus Schoutsen in September 2013 and first published publicly on GitHub in November 2013. [24]In July 2017, a managed operating system called Hass.io was initially introduced to make it easier to use Home Assistant on single-board computers like the Raspberry Pi series.
