1. By using the LM555’s reset pin as the input, the timer can serve as a buffer circuit driven by standard logic levels from 1.8 to 5 V. In the inverting configuration, the trigger line is used ...

The 555 timer IC is an integrated circuit (chip) which is used in a variety of timer, delay, pulse generation, and oscillator applications. 555 Signals and Pinout (8 pin DIP) Figure below shows ...

This circuit is built to repel mosquito using high frequency sound. The design is comprised of LM555 timer which provides the pulse generation and precision timing. It is also a stable controller ...
