The purpose of building this circuit is to create a LED flasher with alternating sequence from the two LEDs where the operation is based on the functionalities of a 555 timer integrated circuit. 555 – ...

A free-running generator built on the standard configuration of the 555 timer can't provide a duty cycle of exactly 50%. That's a well-known fact. Fortunately, there are several ways to get around ...

When working with hardware, whether a repair or a fresh build, it’s often necessary to test something. Depending on what you’re working with, this can be easy or a total pain if you can’t get the ...

Applications of commercially available integrated timers, including the NE/SE555, are fairly limited when used in their monostable mode. This is due to their inability to function with all types of ...

Most toolchains for embedded system include support for random number generation. But if you’ve read the manual you’ll know that this is really just pseudo random number generation (PRNG). When ...

The circuit was designed to create a touch switch that can be used for ON/OFF functions in modern technology. BC547 – NPN small signal transistors designed for general purpose switching and ...
