Title: Timer Tic Beep
Post by: 06awaism on Jan 25, 2013, 07:32 pm
Hi, How can I add 8 Ohm speaker to the schematic below so it beeps every second. Any method that involves an active device (any deice that converts signals to the output like logic gates, 555 timer, amplifier etc) would be preferable but not necessary. Any detailed answer or help will be really appreciated. Thank You Very Much.

Another 555 (http://bit.ly/WAlTTi) is a possibility.
