Make 5v to 24v Regulator With 7805 IC : DIY
มุมมอง 13K4 ปีที่แล้ว
Make any regulated voltage from 5 volt to 24 volt with a simple regulator IC 7805. Make 5v,6v,8v,9v,10v,12v,13.5v,18v,24v with most common ic 7805. #Mr.SM #ArduinoTutorial Remember: Input Voltage should be 2 volt(minimum) output voltage. So, if you want 18v, Input voltage = 18 2=20 volt minimum. Any problem and any question please write in comment . Thanks.

Is it be hot after time?
It do charge the battery but apms are too low around 100-400ma
Al preparar la batería¿Se pone directo a la la moto para el motor de arranque?
Very very slow
Please use higher module for high current rating.
Sar is module Mein 3.7 volt 2 ampere ki battery Lagane se ya module kharab ho gaya what is the reason
Module is not genuine.
I make but not working
Power bank module may be defected. Try with other one. Thanks
This power bank doe not work
And what about ampss
1 amp max. Thanks
Code please
Hello. My problem is that when I am charging the cell phone after 10 seconds the charge is cut off and you have to disconnect it and reconnect it. What is the cause of that? can this protection be bypassed? Thank you very much
The module is weak and over heated. It may be defected. Try with other one.
Thanks for your answer. Cheers
Good
How many battery is advisable to use on the board
Change the module with a better one and add more cell in parallel. It is for verry beginner. We should use BMS for each cell actually. Thanks.
Why isn't it working for me?🙁
I did everything like you did though 😭
May be the module is damaged.
How many hours can it charge before being lowbat? And how many hours should I charge this powerbank?
Please reply. I really need it for a project 😭
Red light will be changed to blue or green when it charged fully. Thank you.
شكرا جزيلا
Please write in english. Thanks.
How much time does this module take for charging 1battery
පැයකට ආසන්න කාලයක්

इस मॉड्यूल से बैटरी को चार्ज करने में बहुत ज्यादा समय लगेगा क्योंकि ये मॉड्यूल बैटरी को चार्ज करने के लिए 0.8Amp ही सप्लाई देती है।
Excelente proyecto muy buen idea muchas gracias por compartirlo

me too, need help
Hello! Can I use battery holders for this project? Sorry if I'm being ignorant but I really need ot for my research study. 😭
Yes and you can use any 3.7-4.2v battery
Hi sir, how do i know when the battery are full?
