Esta bonito el proyecto, pero le veo un pequeño error, cuando se ve que enciende todos los leds ,en el displey solo aparece el voltaje de un led, 2.5 voltios, y no aparece ningún miliamperio , y en el diagrama se ve unas línea negra conectado con el rojo., no se ve que este conectado el amperimetro, ,la presentación está bien, un saludo.
Why there is no current reading? Its working as Voltmeter only. I think Yellow wire and Positive out put terminals should be connected without resistance or use a very low resistor. Then it will show current also.
The working voltage for the meter shown by you is max. 30 volt and it can measure up to 100 volt by using yellow wire. By any way if the DC voltage goes above 30 volt the meter will be burnt out.
@@zarzarel1910 The value should the input fuse have up to the transformer? On the transformer you are using is 500 mA so that what I would use. The current handling of the meter is 10 amps so I would go with that. Again these are for safety, so undrefuseing by 10% or more is always safer then sorry.
What is the reason why the ammeter cannot be used? is it not connected well in the circuit or, by means of the two resistors, the current is limited to a value of, say, 20mA? Thanks for the possible explanation

Wohhhhh wohhhhh very impressive and beautiful video making... ❤️❤️❤️🙏🙏🙏🙏👍👍👍👍
Anh thiết kế bộ kiểm tra những bóng led thật hữu ích
Muito bom, só faltou a medição dos amperes, como no circuito feito com bateria 3,7v, booster e placa de carregamento. Saudações do Brasil 🇧🇷.
درود . مهندس عالی بود . تشکر .
How about the current, no reading ?

I recreated it and it works great!
If I connect thin yellow wire without resistance. Will it show current pls
Yellow wire conecnt 2.2k restance positive series।
Can I use9-0-9 transformer in place of 12-0-12 . Pls reply . If yes then what other changes to be done
Use कर सकते हो।
Amp mtr is not working both videos
Good job ❤❤❤👍👍👍
Thanks for comments।
if i need hight more than 32 volts??
SUPER EXCELENT SIR JI WELL DONE.BEST.
HOWs THE CONNECTION IF I WANT RO TEST THE AMPRE
Selamat atas proyeknya! Satu pertanyaan, apakah ada cara untuk mengaktifkan tampilan ampere untuk mengetahui arus dioda?
For testing we need power supply from Transformer 220V/12V. Can we use pulse source (not transformer)?
can we use higher voltage output transformer like 32 0 32.
can use 32V & 32V = 64vac X 1.34v = 85.7 Vdc. but have to change 2 resistors with higher values and capasitor
@@edyrahmat7905 can we use 5k resistor 1000uF/100v, thank you
In video you are not showing connecting of yellow theak wire of dc voltmeter. Pls show that
Yellow wire conect output positive।
Can I use 1/4watt resistance inplace of 1/2 watt. Pls
Use kar sakte ho।।
But restance jada hit hoga।
Thanks pls . I am not professional but very much eager to learn. It very useful in day today life.

wow.. very nice watching bro.....
Thanks for comments।Your coments are very valuable for me।
почему именно 2.2кОм? как это расчитывается? по чему допустим не 4.7? был бы благодарен как это расчитывается?
Output voltage about 30v dc direct to digital volt amp meter , can it damage the digital volt meter ?
Volt meter range is up to 100v & 30 amps.
Nice. But it can test only one led at a time not the whole strip with series Leds like a commercial tester
Nice work there. Thank you for making and posting this video. God[Bible] Bless you.
Thanks for comments।। Your coments are very valuable for me।।
Good job
Thanks for comments.
If we use 15-015 volt 500ma transformer then we have to change resistance of what value. Pls specify
Use same resistance।
🎉🎉 Спасибо большое красивые видио 🎉🎉🎉 понравился 🎉🎉🎉
Спасибо за комментарий | Ваши комментарии очень ценны для меня...[ Thanks for coments | Your coments are very valuable for me ]
A fuse on both the input and output for safety would be wise
What value should the input fuse have up to the transformer? Or do we need a whole circuit, with varistor, capacitor, coil and fuse?

please draw the diagram clearly so could understand.

Bạn có thể cho biết số cũa điod ,tụ và 2 con điện trở bao nhiêu ohm cám ơn bạn
I only have digital volt meter will this work on that?
Yes work ।Thanks for comments।। Your coments are very valuable for me।।
Và tôi có biến áp 600mp làm được không
meter ampere?
Unless you live in medieval England, you may want to hit mute before watching!!

Ammeter is not used in this circuit. You should have used only voltmeter in this project...😄😃😂😀🤔

Use 500 ma transformer
Ok thank u
Noticed, amber ammeter isn't working

Aap Jo power supply tester banaya hai usmein to ampar Kam Nahin kar raha hai

Positive out put mein 2.2k resistor series hai isliye amp show Nehi kar Raha hai।।
Use only volt meter।।
einfach und sehr gut. BRAVO

why is the ammeter not working?
