The next step is making a LED Flash. After checking some sources and trial runs. I can get a LED to flash slow enough and not look like a Xmas tree. This one flashes at 41 per minute. By swapping the 100K with 220K and swapping the 10k with 2.2K. I got 19 flashes per minute.
I used a 9 volt power supply for now, to keep it portable.
The LED is a 5mm red in line with a 470 ohm resistor. Connected to #3 and and #4 which is positive.
The 555 timer has 8 pins. 1 is negative and 8 is positive. Notice the connections from 8 to 4 and 6 to 2.
100k is connected from 2 to 7, and the the 10k is connected from 7 to 8.
The capacitor is a 10 micro farad (uf) connected to 1 and 2 . The black stripe is the negative side of the capacitor.
All these parts are available at Radio Shack.
Or you can buy one already completed but I had to know how to make one.
I'll have to edit this post a lot but I had to start somewhere.
Now, after this introduction I can go in three directions. Actually solder one on a board, use different lights and go tandem and use a different power supply more suitable to the hobby.
This is just a quick introduction. Buying parts can be intimidating to the :newbie:. Many times I have gone to Radio Shack and just looked into the drawer ,thinking I know what I want, and just give up. I will post the parts in the Technical section. Please post easy questions here.:laugh:
The breadboard has connected holes. abcde are connected and fghij.
