machine sound generator circuit

Countless projects have been developed with a variety of alarming effects. We prefer different sound effects in different places. For instance, in security-based projects sharp and alarming sound is considered the best option, whereas, in the doorbell, the soft sound is found pleasant to the ears. Thus, it is more appropriate to have related sound effects for particular areas. The project “Machine Sound Generator Using 555 Timer IC” is a similar project aiming to generate machine sound solely for industrial applications. However, the circuit Machine Sound Generator Using 555 Timer…

circuit diagram of beeper for automobile flasher

Flashing light is a good way to alert people around but is not the best measure. Ears can hear when eyes cannot see. Therefore using a beeper circuit is the best remedy and this concept has been utilized in modern automobiles and also included in multiple other applications. The project ‘beeper for automobile flasher’ can be implemented in old automobiles (scooters, motorcycles) where there is no beeper circuit along with a flasher. It can also be included in many other alerting projects which employ flasher circuits.  Working of Beeper for…

circuit diagram of 555 ic tester

NE555 Timer IC  is very popular and one of the most commonly used components in electronics circuits. NE555 Timer IC is also called Ideal IC since it offers multiple features like multipurpose functionality, low power consumption, small size, and durability. When we work on a particular project and it doesn’t work the way we wanted, before the circuit we doubt whether the IC used, is working or not. More or less, blaming IC is reasonable since IC is the combination of many more components or IC itself is a combination…
