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 ... For user ...

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 ...

Abstract: Small computer board platforms, such as Arduino, Raspberry Pi, and micro: bit are very common, cheap, and useful tools to teach modern technology, coding, and experimenting in different ...

A simple transistor circuit offers an effective solution to this problem. The I 2 C bus is highly vulnerable due to its design — both SCL and SDA “float” at high potential and are pulled low by the ...

Abstract: The noise margin (NM) of an inverter is an important feature for the operation stability of the digital circuits. Owing to their simple structure, easy processes, and relatively high gain, ...

While developing a vacuum system used for homemade PVD sputtering aparatus I felt the need of a simple and cheap vacuum gauge that ... interpolate the points from the datasheet and then place it into ...
