Arduino Mosquito Repeller

In this instructable I’m going to show you how to build a mosquito repeller using an Arduino. The repeller is in the form of a shield that plugs into the Arduino board and the frequency of the repeller can be changed easily. This project is ideal if you are going camping or hiking outdoors, this device produces a sound of 31KHz Frequency which acts as a mosquito repellent. The frequency of this device can be adjusted and at 23kHZ to 54 kHz it also acts as a dog whistle. Human ears are not sensitive to these frequency ranges. You can also view the video below on how to build this project.”
