CE 3.2 Project Background
CE 3.2.1 Characteristics of the project
In public places, water availability is very crucial and hence, I targeted the public sector
for developing a system that will allow dispense of water through inputting proper coin. I
developed the system that could be used in public for dispensing the water after entering proper
coin as per the set budget and dispense the necessary amount of water. I developed a system that
can be operated within 5V and that will be constantly supplied within the system and an object
will be placed in the place of water dispensing area and hence, the water will be dispensed. The
project was developed considering the following block diagram:
