Title of this project called ‘4 in 1 Automatic Handwash’. The purposed of this project is to help people to get rid of illness and germs infection. This project is using Peripheral Integrated Circuit (PIC16F877A and L293D). This project is obtained from combining two circuits which is from handwasher circuit and hand dryer circuit. The IR sensor is used as a sensor for this project. The software used for this project is ISIS which is used for simulation circuit, MikroC, used for PIC programming and PCBWizard, used to get the PCB layout. This handwash will functioned automatically by sequence of flow. Firstly, whenever the IR sensor detect a hand below the tap, it will switch ON the motor of water, soap, hand dryer and hand sanitizer in sequence that are set by the program in the PIC. This will only work when user keeps putting their hand below the tap. This is because, when user furthers their hand from the tap, the IR sensor cannot detect the hand and this will automatically reset the whole process. This project assures their user to get a clean hand whenever they used this hand washer. This is because this handwasher provide all the needs for clean hand in one place.
