Electronic pest repellent / Ahmad Qusyairi Muhamad and Khairul Khaliq Hisam

Pest carried of various negative effects such as diseases. These diseases can even prove to be fatal for the poor, who have little access to medical care. Methods of repelling pest have been around for a long time. This project also will be one of the ways to avoid the disease. Electronics Pest Repellent was invented to overcome the problem. This project used electronic components combine with DC source to make this project completely done. This project uses microcontroller and 16MHz crystal, and small speaker. The electronic components and their function are combined into a bread board such as the microcontroller ATmega328P that functioned to produce various frequencies and make it as our output to repel various pests. The circuit constructed and the simulation was tested. The simulation result was same as the expected result.
