He reads a voltage from a 555 timer using the ADC on the microcontroller. At first glance it may not seem like a great source of randomness, but he performed some testing and the results look ...

If you’re not familiar with the 555 timer, suffice it to say that this versatile integrated circuit is probably the most successful ever designed, and has been used in countless designs ...

In the book, I walk the reader through the simplest use of a 555 timer to rather advanced techniques and tricks through the hands-on building of fun projects. But not every project made it to the ...

Used in a variety of timer, pulse generation, and oscillator applications, the 555 was designed in 1971 by Hans Camenzind. A favorite for many engineers, the 555 is still in widespread use due to its ...

There are a vast number of 555 timer applications that span a ton of industries, including for PWM pulse-width modulation (PWM) and pulse-position modulation (PPM), which are widely used in ...
