Where to Buy

Recommended place to get parts; is the best place to buy electronics and components base on the massive seller choices, great pricing, and the best Money Back Guarantee buyer protection program. is the best raw material supply house I found who provides the most accurate Cut-To-Size material and excellent in pricing.


Practical Projects

WiFi OTA Arduino IDE

OTA (Over the Air) update is the process of loading a new firmware to ESP8266 module using WiFi connection rather than a serial communication. This type of functionality is extremely useful in case of no physical access to the ESP module.
The ESP8266 also provides Web Server functionality. This feature operates completely independently from the serial AT Server. The web server responds to http GET commands received form the Internet via the built-in Wifi capability.

HC-05 OTA Arduino IDE

HC-05 module is an easy to use Bluetooth SPP (Serial Port Protocol) module, designed for transparent wireless serial connection setup. Serial port Bluetooth module is fully qualified Bluetooth V2.0+EDR (Enhanced Data Rate) 3Mbps Modulation with complete 2.4GHz radio transceiver and baseband.
PS. Project's data pending release.
