Mosquito repellent using ultrasonic / Nizaar Suhairy Johari and Faizal Amir

First of all, this report is to state clearly about the project made which is the Prototype Mosquito Repellent using Ultrasonic. This project is made in order to fulfil the objectives that been made which are to develop and study the effectiveness of ultrasonic towards mosquito for repellent. Significantly, this project able to study the repellent device as mosquito using different range of frequency. The main component of this project is the Decade Counter IC CD4017, D flip-flop IC CD4013, Ultrasonic Transmitter Transducer and Ultrasonic Receiver. These transmitter components will be connected decade counter and D Flip-flop, gives the input signal from the user and the Ultrasonic receiver act as mosquito linked together with the decade counter CD4017 will get the signal and the buzzer will on. The circuit will connected directly with the power supply which is battery so that the design of the transmitter and receiver is flexible enough for user to use this prototype. Therefore, if this project is success, it will able to ease people with improved technology than the old traditional mosquito recoil.
