Easy to follow and straight to the point. Thanks a lot.
🙏
Was exactly looking for this to convert a 2x AA battery powered device to operate with 5V USB power bank.
very good, you explained something so simple that everyone rolls around to say or do. keep posting video.
Thank you so much 🤗
Yes iam try supar 🎉 5v to 3.3v 👍🏻
👍
This is slightly misleading as under load, the resistors will have to change to keep a constant voltage. Variable loads whose current changes will not work with this setup. Dropping voltage like this would work with converting a signal from 5V to 3V. Maybe the limitations of this method could have been discussed / conveyed better.
I made this and tried to drive a wall clock movement (designed to use 2 x 1.5V C size batteries) and a tiny motor. Both don't work. The voltage measured is 3.3V but it does not make a device work.
Check your amperage.
Input 5v 2a output 3.3 but the 3 v led not have enough brightness
Will it drain the power bank charge quickly?
Thank you! Great and helpful 👍
en el multitester puede marcar 3 3 v.pero en la accion no mueve nada pruebalo con un motorcito pequeño y vas a ver que no se mueve
Gracias por la ayuda, pero hay otro circuito en este caso, se puede ver en el siguiente enlace 🙏

good work
tnx🙏
I have an ESP01 module that requires 3.3v .... Is this the best for that kind of use.. it dosnt require that much current???????
Hi dear friend. You need a constant voltage for this, and it is recommended to use the video circuit below

Hi Nice Video. - if i was to use this method to drop voltage from 5v to 3v for some small fans being powered by a Battery would the battery drain faster due to the resistance of the resistors ??
10k has more resistance than a 50 ohm, why is it smaller? Should more resistance mean more material aka a bigger resistor? Or is higher the ohm the least resistance??
The size of the resistors is the same.
Their size depends on their ability.
For a resistor, 1 watt is greater than a 0.5 watt resistor and 0.5 watt is greater than a 0.25 watt resistor.
I hope the explanation was useful to you 🙏
I can't find 10k resistors on our market and i only have one 10k resistor.... what other alternative resistor can i use?
Hi
It is better that you use the circuit in the video below.

i have an output voltage of 4.5v, how do I connect two resistors of 10k and 18k ohms to have 2.8v?
You can use several diodes.
Each diode causes a voltage drop.
Or use a regulator.
You can use these two videos:

1.5v ke 2 normal cell se muje 5730 ki 1 smd led chalani he to kitne ka resistance lgana pdega bhai..
1 smd ka watt 0.5 pr 0.2 hai... pls help
You can use 0.5 watt 33 ohm or 0.25 watt resistor and the code is SMD 330.
@@TricksOfAli 5703 smd ek hi pis ko 2 normal cell AAA se chlana hai to konsa resistor use kru bhai..
Hello, thank you, I did this, I connected it with a 5-volt mobile charger, but it gets hot, what is the reason!
👌👍👍👍
Fiz conforme seu exemplo e quando ligo os cinco volts, todos os diodos aquecem demais, derretendo as soldas entre os diodos.
Fala comigo
Não temos diodos neste vídeo. Se você quiser usar diodos, consulte os seguintes vídeos

Olá, eu fiz com 4 resistores de 1k e três diodos 1n4007 para ligar uma campainha.
Excelent work 👍

un dato a la hora de medir una resistencia no uses tus dedos ya que tu cuerpo también hace de resistencia y la lectura puede variar
Hola querido amigo . Sí, tienes razón y definitivamente seguiré este punto de ahora en adelante.
It works for converting an 5v USB cable to 3v?
How many amperes do you need in the output of 3 volts?
Sir 5 V to 2 V me kon sa resistor lgega pls koe bta do
15K + 10K use karo.
This is not the way to do this. You should us a voltage regulator like the AMS1117-3.3 or similar.
The resistor values are off but this is how you convert 5v analog signals into 3.3v analog for a microcontrollers input. Couple this with a opamp for circuit isolation between the sensor and uC
Nice video keep it up
Thank you for your support

Value of resistor to get 4.5v output..?
you can use this video

In this circuit, we use diode voltage drop. Almost every diode decreases 0.5 volts
Regards, good video, would you be so kind as to answer a question, the voltage at 3.3 if I put a 3v pocket radio on it, the voltage would drop or it would remain at 3.3, thanks.
Hola! Puede servir como level shifter entre arduino de 5v y un sensor de 3.3v solo para los pines logicos?
Yep.
thanks
I have 3.7v led how to connect 5v usb charger what resistir i put in led
Hi dear friend .
Calculating the resistance requires LED specifications.
For example, below the calculation of a 3.3 volt 20 mA LED with a 12 volt power supply :
Forward Voltage = 3.3V
Forward Current = 20mA = 0.02A
R = V / I
R = (12V - 3.3V) / 0.02A R = 435 ohms
hi i follow your method and get 3.3v but when connect to main circuit board it become 1.2v .how to solve?
it's bcoz the ampere is too low.
Love it
good
Hii ..... My Keyboard is apple model no- A1255 1.3vot 3 1.3x3=4.5vot battery So how to convert 3.7volt battery to convert 4.5volt..??
Use a boost converter module bro
Os resistores vão superaquecer?
Este circuito tem correntes muito baixas, por exemplo, até 100 miliamperes. Em correntes mais altas, enfrentaremos uma queda de tensão. É melhor usar o seguinte circuito.

@@TricksOfAli ok, muito obrigado pela atençao.
de nada🙏
Fala comigo sobre estes diodos.

fake video avi banaya but kaam nhi kiya
No bro, this video is real.
Não funciona. Vídeo falso.
fluctuating 3.3v
Yes, this is an example, I will put better versions. thank you for watching🙏
@@TricksOfAli I am quite ignorant in the matter, but wouldn't a capacitor be enough to stabilize? if so what spec should it have?
Yes, a capacitor can solve this problem to some extent.
I think a 6v 100uf capacitor could be good.
In the future, I will put a better version of this circuit in the video
@@TricksOfAli thanks

hello friend, sorry for the inconvenience, I wanted to ask you if this set is used to lower the 5v voltage of a laptop usb port to 3.3v??😇😊
Hello, dear friend, it is better to use the circuit below

yes me also i don't know what is the problem
