1-11-2015 | The first part of this series introduced the basics of programming in Assembler and the hardware fundamentals of the PIC controller used. Pa...

1-05-2014 | A timer circuit that turns on a pump for a short time every five minutes can be easily made using the famous 555 IC. Unfortunately, it's alm...

1-01-2014 | The celebrated ‘555’ IC was originally developed as a timer device, but over the years this golden oldie has been used in all sorts of other...

19-01-2013 | Ever heard of 1GΩ resistors? The 555 timer here has a duration time of about 270s; by using a high resistance value of 1GΩ, no electrolytic...

1-07-2005 | Anyone who has designed circuits using the 555 timer chip will, at some time have wished that it could be programmed for longer timing perio...

1-12-1996 | Strictly speaking, the title 'current limiting' is not entirely right, since the circuit itself does not limit, but detects. When the cu...

1-07-1991 | Many electronic circuits frequently require the brief delay of a pulse. Such a delay, here between 100 µs and 100 s, is easily provided...
