With the use of boards such nodeMCU and others that also incorporate the ESP8266 module it is possible, very simply, to upload sketches wirelessly, regardless of the USB connection, from the arduino development environment. This greatly facilitates the maintenance and updating of all those IoT devices that we design in this way. Implementation method is…

After several Arduino-based designs with the use of external Bluetooth and Wi-Fi modules, I decided to purchase a pair of NodeMCU – ESP8266 boards that incorporate Wi-Fi and BT connectivity and can be programmed from the arduino environment. There is also a lot of documentation about these boards. The idea is to use them to…
