Power Supply (x1): 5V–12V DC adapter for powering the Arduino, or in my case, we use 2S Lithium-ion battery connecting to Vin pin. Below you can see the circuit diagram used in the ... starting from ...

on our Arduino Uno. This LED is connected to the Arduino’s digital input/output (I/O) pin 13. We ended that column by plugging one end of a flying lead into the header associated with this pin (the ...

Arduino UNO SPE Shield adds Single Pair Ethernet (SPE) and RS485 to Arduino UNO and compatible boards, notably the Arduino UNO R4, via a Microchip LAN8651 SPE controller. Single Pair Ethernet relies ...

Place the SIM800L library folder into your \Documents\Arduino\libraries folder. You may need to create the libraries subfolder if its your first library. Restart the ...

An Arduino Uno (CH340G clone) reads temperature and humidity from a DHT11 sensor and computes 10+ environmental metrics (heat index, dew point, enthalpy, humidex, vapor pressures, etc.), outputting ...
