Hello,
everyone..
I'm doing my project on WiFi based application.
as part of that, i managed to get channel response for particular set-up.
the plot of the response is as shown in attached image.
As visible in image the plot contains 30 indices on X-axis and magnitude on Y axis.
and the...
NO!!!
simple speaker only capable up to 20KHz frequencies....
It is designed for that purpose only.
If you want to build any Mosquito repeller or insect repeller, You Need Ultrasonic Buzzer/Tweeter.
Just google with "Ultrasonic Buzzer" "Ultrasonic Tweeter" "Piezo electric Buzzer"
You will...
Its in ultrasound range.
Small mammals like cats and dogs sensitive to. 22 to 25KHz
Insects like mosquito and flies to 38 to 44KHz rats to 60 to 72KHz.
You need special high frequency tweeters to produce such sound.
First Please clarify about your familiarity with types of microcontrollers...
Do you know All microcontrollers well?? means AVR, 8051, PIC and many more.
IF you are good at Atmel AVR series than typical Arduino (arduino UNO)will be right choice.
If know PIC than go for it....
If you are...
I think it terms for using in photovoltic mode.
in which there is zero reverse bias applied to photo diode for producing voltages rather than reverse current.
Hi...
Im novice to AVR mcu and its various programming/prototyping methods.
I had installed atmel studio6, managed to get STK500 programmer, and after some attempt succeed in programming simple LED blinking program on mega8515 available on STK500.
apart from this i don't know much about...
for getting any functional output from OPAMP we need to provide some source voltage....
If input impedance is lower then it will draw more current and will overload our source....this is undesirable.
such situation will never happens if there is high input impedance....means OPAMP drawing less...
this is specifically related to voltage amplifier.
for current amplifier it is exactly opposite.
for transconductance amp input and output resistance both should be high
for transresistance amp. both should be low
So it depends on application configuration
Actually u r right. LED produce around. 1.3v
I just considered it as a pn junction diode.

The equation is just for reference
in your circuit it is not valid for all t (time)
Capacitor will charge only upto forward drop across LED. remain there forever
It will not...
charging equation of RC series circuit.
vc = v(1 - e-t/rc)
In this case capacitor will never charge more than 0.7 V that is LED's forward voltage drop.
