Well we go to my project. A circuit for months tried to take an effect as an "open and close" in a LED bargraph and only found circuits with microcontrollers, which use not know yet. Until a site of one of the magazines that I buy, I found this circuit, hills and found it very good.
Below the list of parts, instructions on how to assemble and some images:
1 555 timer
1 4017 counter
1 LED bargraph or 10 LED's
2 4k7 resistor
1 1K resistor
1 1M Potenciometer
1 10uF/ 16V capacitor
Step 1: The Instructions
Look at the first figure in step one: in place of the LED module to place the diode (Figure 2).
The diodes are of general use, the CI's case is mounted in PCI should be with their respective sockets to facilitate the exchange in case of burning.
and that. I hope everything in its right to the next assembly and instructables.
