Oscillator tutorial in HD!

This tutorial covers the basics of oscillators - what they are, what they are used for, and it shows a couple of demo circuits with a sine wave oscillator and a square wave oscillator. Clock generator circuits for digital processors are also briefly mentioned. Don't forget to vote upvote!

So if I build this circuit and connect an Antenna instead of an LED to the output I be sending out a signal correct?

[Afrotechmods]

@JGalva88 yup. Don't expect it to radiate very far though.

Sorry to bother everyone, I have a science question I need to do to calculate Oscillation Amplitude?... I have googled it and not really found anything beyond overly complex equations. To get Oscillation Amplitude do I measure from peak to peak? (Top of the top peak to bottom of the bottom peak etc..

[Afrotechmods]

@lacerta999 Amplitude is defined from 0 on the vertical axis to the peak of the wave. So for a perfectly symmetrical sine wave the amplitude would be half of the peak to peak voltage.

Hi!!! Can I use the pin 3 of this 555 oscillator to trigger the gate of N channel MOSFET? ( IRFZ 44) I would like to trickle charge a 2 volt lead acid battery from a 12 volt Battery.The load will be the 2 volt lead acid battery. THANKS

[Afrotechmods]

@HHOhybridBuilder You can use pin 3 for that yes, but I don't see how that would help you trickle charge a battery

lmao A MEXICAN WAVE!

[fbpoulsen]

I love your tutorials!

[oozytes]

Thanks for taking the time to make this video;)

Was hoping for an inductor/capacitor based oscillator tho :(

[XxWearsMexX]

New in electronics here... Can I use different capacitors while building the square wave oscillator? (555 timer)

[lolypopboy777]

How can i make a saw or sawtooth?

[gammainn]

The second circuit that's shown. is it possible to modify it to use with a guitar, controlling it's pitch with a pot or something you could use as a "whammy bar" ?

[TheDrivenMind]

@Afrotechmods Well then, this begs the question: What determines signal strength, how can I measure/calculate it, and what is the most effective way to generate strong signals?

@ 1:42 i can host my own Rave, classic LOL - Man you are funny.

[jdflyback]

@Afrotechmods what is wrong with powering the Lm324 with a single nine volt battery and calling the negative terminal ground? Please respond

[fairyheli2]

so with a transforer you get an ac output?

[JippysProfoundings]

You sound like my tech teacher from middle school? Is that you Mr Beck?

[stickygreenbeats]

have fun pretending 2 be r2d2 lol
