This consists of the mini project related to Electronic Engg. like Automatic Irrigation Systems, MUSIC REACTIVE LED circuits, and Gas Leakage Detector with implementation steps, advantages and disadvantages. In Automatic Irrigation System. The automatic irrigation control using a microcontroller has been experimentally proven to work satisfactorily. We could successfully set the timer and managed to control the motor over time. This process not only records values of temperature and humidity it also contains the engine accordingly. Analyzing the weather condition motor will automatically...
