4pyros Well-Known Member Most Helpful Member Nov 22, 2011 #4 You may have the wrong mic then. Any specs on it? Some need power to work.
mvs sarma Well-Known Member Nov 22, 2011 #6 have the sch modded like attached. The condenser mic body goes to negative as you know. Attachments modded.PNG 186.6 KB · Views: 246
Boncuk New Member Nov 22, 2011 #7 Besides the microphone connection the trigger input pin of the timer IC should always "see" a potential. If you use R1 and D1 as in the attached circuit schematic the circuit should work. Also 470Ω for a current limiting resistor is a bit high of value making the LED very dim. Using 220Ω the LED current is around 17mA. At 180Ω the LED will be drawing 20.7mA. Boncuk Attachments CLAPSWITCH.gif 12.2 KB · Views: 286

Click to expand... hi, 'specs' is an abbreviation for Specification, the Specification is the performance data for the device, thats printed in the datasheet for the device.
