What is the point of reviewing a cheap timer module, especially if it is based on the ubiquitous 555 timer chip? Recently I got an ‘updated’ version of the common 555 timer relay module. This time it ...
Anyone who has designed circuits using the 555 timer chip will, at some time have wished that it could be programmed for longer timing periods. Anyone who has designed circuits using the 555 timer ...
Many of us could sit down at the bench and whip up a 555 circuit from memory. It’s really not that hard, which is a bit strange considering how flexible the ubiquitous chip is, and how many ways it ...
