Presently, conventional wall switches are located in different parts of the house and one has to physically go near them and press them to turn the loads on/off. The home automation is one of the most emerging trends in modernization of home appliance control. ![]() It is believed that the design will go in long way in educating power electronic engineers in the arts of design using Arduino also, a mass production of the device will accentuate Small and Medium Enterprises SMEs in developing countries with its concomitant economic advantages. Protection devices like circuit breaker overload and phase failure relays are recommended in order to prolong the life of the Water pump. The design recommends improvements in the area of sump control so that its low water level could disable pump thus preventing it from running dry. An option of I2C LCD codes was written thus providing advantage of using only two analog input A4 and A5 pins instead of 4 to 8 pins in other configurations thereby allowing other pins dedicated for other tasks. Liquid Crystal Display function displays the level of water on the 16 × 2 LCD thus: Very Low, Low, High and Very High. Proteus was used to simulate the design while the project was implemented on breadboard. From a well spelt out algorithms, flowchart was drawn, from which Codes were written and compiled on Arduino IDE. The paper explains utilization of Arduino Microcontroller to automatically control level of water in a tank.
