555 TIMER MADNESS – my new breadboard.

March 10, 2008

the other day i bought a breadboard with the aim of doing some serious learning about electronics. After a few failed attempts tonight i managed to complete a working 555 timer circuit that switches between 2 different coloured LED’s. I knows it’s a fairly minor feet but it’s a fairly exciting start none the less. The circuit involves a capacitor that is alternately charged and discharged to control the 555IC between +9v and -9v on the rail. YAY… in other exciting news I made (on my new breadboard of course) an accurate to +-100mv a 5vDC voltage regulator circuit which involves capacitors, transistors and lots of other fun stuff. Here’s the photo’s of my breadboard exploits.
