Judging from the numerous references I have received, this electronic circuit, hobby circuit seems to be rather popular. Many
published circuits which flash LEDs need 3 or more volts. This electronic circuit uses only a single inexpensive C-MOS IC and flashes the LED for a full year on a single 1.5 volt AA alkaline
battery cell. The circuit uses a charge pump technique to provide the LED with the needed voltage. This electronic schematic will only work on red, green and yellow LEDs. It is not
be able to flash white LEDs. |
