When I searched through Github for DHT libraries, I found a lot of them, some of them offers additional functions, some of them only basic temperature and humidity values. I wanted to combine all interesting functions into one library. In addition, none of the DHT libraries I found were wri...
The Visual Micro debug upgrade is supplied with a few basic working examples such as Digital Pin Viewer, Analog Graphs and other examples, found on the internet and adapted to be intelligent visualizations. All of the example are supplied with full source, attributed to the original authors, and...

we need an HC-05 Bluetooth module for the smartphone communication and some capacitors and resistors. Of course the brain of the robot is an Arduino board, and in this case that’s the Arduino Mega because it’s the only board that can control more than 12 servos using theServo library....
