The presented automatic LED candle light is very straightforward and fairly reliable with its operations, I have explained it through the following explanation: The 0.33uF/400 V capacitor along with the four diodes and capacitor forms a compact transformerless power supply circuit stage for powering t...
ABSTRACT This automatic emergency led light used in night at emergency time when the power cut or off by some region. This emergency light takes 230V AC and it converts it in 12V DC and charge the battery which is used in this circuit. The power of the battery is used that time when ...
The project is to make an automatic door for a hen house, I would like it to be controlled by dawn/dusk to run a 12v motor to open the door then reaching a limit switch to then reverse motor direction when it is dark returning the door down to a second limit switch placed at the ...
The client program is implemented using the C++ Arduino API [26] to run on the microcontroller deployed at the weather station. The weather sensors are gathered into a pool of S sensors: Atmospheric Pressure (AP), Air Temperature (AT), Relative Humidity (RH), Rain Gauge (RG), Wind Speed...
