My wee 555 timer circuit!

[Terry01]

I have a wee "555 circuit" made up on a breadboard that's been in my 1 of my desk drawers for well over a year now!
I love adding in a couple more LED's or changing the capacitors or resistors around and measuring the changes around the circuit on 2 or 3 meters,,....4 or even 5 if it's the weekend and i'm really going at it!
Every newby should make something like this up and spend a wee while tinkering with it. It's amazing what you can learn from a simple wee circuit!
The 555 is such a simple wee chip but it's so versatile!

The 555 really is pretty amazing, and as I recall it almost didn't get developed. Even now that a microcontroller can do just about anything a 555 can do and for about the same cost, I still like to use the old 555 now and then.

Yes, i'm sure I have read that too James. It's survived the "test of time" as they say right?

I just went and read some of the Wiki info about it just now!  On the go since 1972, 1 billion per year(estimated) produced, the most popular IC ever made.....yada yada yada....!

I'm going to do the same with a couple other chips and again just leave them made up so I can "tinker" with them and see what and how every part of the chip is working. I know for me I had a few "I understand now" moments with that simple wee circuit.
