I use 3 390ohm resistors instead of 3 330ohm resistors and 330K Ohm resistors to replace 100ohm resistors and C1815 NPN Transistor replaces Transistor BC547, can you?
Yes for resistor, but about the C1815 I can tell you that it is equivalent and it should work, but in practice I do not have any at home to give you a test and give you 100% confirmation
Why do I attach 2 white LEDs, but if I have one, when I turn the circuit on, it emits white, and the other one, it emits blue light, what is it???? I don't understand! I hope you can explain this to me
Hi, you have probably mounted one white and one blue led. The high luminescence LEDs are all trasparente, but then they emit light of various colors such as Yellow, Orange, Red, Green, Blue etc.
super video,i like your channel , if you like planted tanks with snails, shrimps or frogs look at my vids to chill and relax,nice greetings from germany*****;
Greetings from South Africa. Love your vids
Thank you DJ Stoop!
Magnificent project.👍Greeting from Saltillo, Mexico.
Greeting from Italia:)
0:35 you forgot one T at the 100k resistor. love your projects :D
Kostanj42 you are right! thanks:)
I want to buy this type of pcbs
Hi, in the description of my videos you can download the PCB files, then you can buy them on JLCPCB, choosing the color and other small details
In the place of soldering 2 wires, can I use a 2-pin domino to supply 9V power?
Yes for the PIN, but do not power more than 6v DC
Can you make a 50 led vu-meter PCB from JLCPCB and use led graph bars insted of normal leds?
Hi, it's scheduled :) I don't know when I'll be able to do it.. I have so many ideas and little time
Hello.
Nice simple project. Can it operate with Vcc about 9V?
It could, though you may want to increase the resistance of the current limiting resistor to protect the LEDs.
Without changes no, you should add an LM7805 (5V regulator/stabilizer) before VCC, with more than 6V the transistor could break.
And with 5 volts?
5 - 6V are the voltage I recommend to use
@@mpachol88 What about a resistor of 1K in series with eatch led?

Does any Photoresistor work or is it a specific one that you used cause mine isn't functioning on your PCB project
Hi, i use a 10K Photoresistor
👍
:)
How many volts are you powering this circuit?
at 5v DC
@@Stefano91ste Can I use a 9V battery?
If I power it with a 9V battery, is it possible?
Not more than 6 volts!
The best project ...
Thank you!
@@Stefano91ste
can you make a project with a motion sensor connected to the telegram application?
Man thts awesome
Thank you :)
