- Опубликовано: 3 апр 2020
- A tutorial on how to make an Electronic Piano circuit using 555 timer IC and a few other electronics components. This circuit consists of a number of push button switches (similar to different keys in a piano) which, when pressed, produce sounds with different tones via a speaker. Explanation of how the circuit works is also included in the video.
Link to the project page and circuit diagram: elonics.org/el...
Components Required:
* 555 IC
* 8 Ohm Speaker
* Momentary Push Button Switches x 6
* Capacitors: 100nF, 10uF
* Resistors: 6 x 1K, 4.7K
* Breadboard
* Few Breadboard Connectors
* (5-9)V of Power Supply
This circuit uses 555 timer IC in astable mode to generate continuous clock pulses. These pulses are passed into a 8-Ohm speaker and it generates audio with different tones depending on the frequency of clock pulse. In order to understand how 555 timer IC works in astable mode, you can go through the explanation part of this video: • Adjustable Flashing/Bl...

finally found what i'm looking for after around 50 videos on youtube.
The way you explain how to build each circuit, and how it works, is brilliant! I'm definitely going to share this, as it is really useful for learning breadboard electronics. Thank you for this :-)
You're welcome :)
I love what you made i am gonna share this too @aidanwansbrough7495
Hasta yo entendí y eso q no hablo su idioma
Success is not a milestone,its a never ending race for perfection , thanks
waah ji waah
Thanks for this, there is a lot of cool beginner stuff you can make with a IC 555 Timer apparently :)
Yup, that's true!
It was a fun project. I liked it
i have never seen like this teacher oF DE before
Nice project this project is working 👍🏻👍🏻
Your videos are so well-made! I love your channel and you are a big help to me.
WORKS PERFECTLY
Beautiful and amazing. This is the pure analog sound. Thank you, thank you for this.
You're very welcome!
Superb bro.its amazing
Thank you
Great video. Just FYI, the equation for R2 is incorrect. Either the "f" in the denominator of the first term needs to be replaced by "2f" or the 1.44 in the numerator needs to be replaced by 0.72. You got the divide by two for the second term (1k/2 = 500) but the first term needs to be divided by 2 as well.
Nice project👌
Thank you
What happens if we push 2 buttons simultaneously?
If you looks up circuit diagram. You will notice there will be two path for current.
1. a path that have 1k ohm (lower pitch)
2. a path that have no resistor. (higher pitch)
Current will chooses 2.
Aka. It will short-circuit.
The result of sound is from button that have higher pitch
well explained bro
I recreated this circuit in my lab, but used a 0.15uF capacitor and 910 ohm resistors instead of the 1k resistors. The output was very faint. Is there any idea on how to adjust the circuit to where it outputs like yours?
sir you are a great teacher
Thank you!
Good job - keep it up
Excellent video, I"m impressed!!
Whole tone scale!
Play some Debussy!!
What if we want to press three buttons at once..so as to make a chord
Thank you so much ,sir.
This video is helpful in my project.🥳🎉
What would I have to change if I were to put 11 buttons on it? I have it on a circuit, but the same capacitor, voltage, etc. It’s not working.
Thanks man, great explanation.
Great project
Thank u bro this video a lots me in my project
Welcome :)
Very well explained
I'd like to put some switch and led lights, but confused as what Resistors to use
what is the use of the 10microfarad capacitor connected to pint 3 output
Could you pls tell how to make its layout for pcb
And yes this is amazing 👏
Hey! I made this project but all the switches are producing the same sound when pressed...can you help me with that??
Love ur voice❤️
Aptly great vedio...... ✌️
Can v use 3300 ohm resistor instead of 4.7 k ohm resistor??
@@vaishnavicas1623 Yes, you can
Thank you
Upload its circuit diagram and components list here please
thank you
Good bro..
Hey can u pls help me to derive frequency formula which you have written directly?
Hello, I am looking forward to make this project. But I am in need of help. I want my circuit to have 3 buttons, one playing f1=523Hz, f2=587Hz and f3=659Hz. I am using a 100nF capacitor. I have no clue what resistor values I should use, I tried looking for some calculator or formulas, but I didn't find anything useful. Could you help me, please? Thank you in advance!
This a very good explanation, thank you , I think I would like to put a pot on each button so I could fine tune the sound ?
Yes, it should work given the pot for each push button is independently connected to 555 IC. Instead of cascading them as shown in the video.
100 nf is not available, so which other value I can use to replace it
What's the use of the 10microfarad capacitor attached to the 8ohm speaker ??
is it used as a high pass filter ??
Sir i used 100pf capacitor instead of 100nf and it doesn't work sound coming out the the speaker is very very low..
Now it's work but my first button not make tune its like switch!
Why do we need the other capacitor of 10uF ? what is the purpose of connecting that capacitor to the output signal?
Did you solder the connecting wires with 8 ohm speaker or just connected the wure in the8 ohm speaker. What did you do pls tell
Ckt diagram bhi dikha kr bnte sir to ache se samjh aata thora slow boliye
Brother plz keep making videos
Sure :)
I have a problem my 555 keeps on giving output without pressing any buttons
Can I make a piano as good as the one available in market .
Is that info available somewhere :)
For all the other keys ?
Can I use 100uF capacitor instead of 100nF and 1uF capacitor instead of 10uF sir please tell me as soon as possible sir please
100uf instead of 100nf will not work as frequency will reduce.
But 1uf instead of 10uf might work.
@@sidtronics Thank u sir
@Shrinivas TN You can try using a 100R in place of 1K and 470R in place of 4.7K and 1uF in place of 100nF. But keep in mind that there will be a lot of power drain through the 100R between Pin-6 and positive rail.
can you please let me know the power of the 8 ohm speaker.
My 4.7 k ohms button didn't work? what to do
Hi, I'm interested in learning electronics especially for Arduino. But I have 0 basic in electronics. Which video you posted in this channel is for beginner like me?
You may start from the first video of 555 series: ruclips.net/p/PLtnycejpkuLXLOv0d37J4JOXKtAnz_BBo
Sir can you please provide the product link of the project
Where to buy the 8 OHM SPEAKER can anybody share the lino
Hello good morning, I ask you a question, how do I do so that instead of having buttons, the buttons are replaced by arduino pins, that I automatically play in random? make me understand !? let the melody be made by the arduino randomly
Hello Good Morning, Arduino has the capability of generating various frequencies and you can randomly choose a particular frequency and drive a speaker. This might help: create.arduino.cc/projecthub/rahulkhanna/arduino-tutorial-mini-piano-08f8b8
circuit not working sir
Me too
Will this work without the 100nF Ceramic Capacitor?
No
Actually it could work with a 0.1uF electrolytic capacitor, which is equivalent to the ceramic 100nF capacitor.
Why do we need another capacitor(10uF)?
I made the exact circuit but still it is not working
Sir is this mono stable ,bistable or astable timer plz tell me
Bro nyc explanation..
Make a video on remote control fan..using tsop1738
Sure
Which buttons are what keys on a piano?
Can i use Jumper instead of Connectors?
Great Work!
Btw my channel is also based on electronics.
I've seen it. Way to go!
FYI that's a counterfeit breadboard- ruclips.net/video/VerbEZtACwQ/видео.html
Can we use 4Ω speaker instead of 8Ω ?
Sir ,if I give 5 volt power supply then what are the changes I have to made
No changes are required. You can directly use this circuit with 5V.
@@elonics ok thank you sir I will it 😊
Can I use 15 ohms speaker?
Can we use a 3300 ohm resistor instead of 4.7 k ohm resistor?
Yes, but frequenzy will be higher
Can we use a 16k ohm resistor instead of 4.7 k ohm resistor? ( i just want to lower the frequency)
Yes, that should work
@@elonics i know this is stupid question but can i use 8 ohm 2w speaker ?
@@ongtran88 Yes, should be fine.
@@elonics Can you explain the role of 10uF uF (Electrolyte) Capacitor in the circuit ? Many thanks !
I mean why did you choose that value ?
What battery u r using?
It’s not working bro please help me
Bro use also buzzer
Can the 4.7k resistor be replaced?
Yes, you can experiment with different resistors with values close to 4.7K
😀😀😀
Will it work for Astable mode ?
Circuit itself is based on astable mode
@@sidtronics ok thanks
Where did you purchase the speaker?
It's not work
Seems like it's a little out of tune
Can i use it for my mini project
Yes, sure
ITS AN ORGAN, NOT A PIANO.
