This is because 555 timer in this project is used as a tool to help produce ultrasound frequency in 20khz-some gigahertz scale. or also known as astable multivirator. And its output will be through the transmitter which has a production frequency of 20khz-40khz which is suitable for special hearing for insect around 15KHZ-38KH
