How To Make 3.7 Volt Battery Level Indicator | Low And Full Level Indicator |By- Aayush's Creativity 

So, how are you? My name is Aayush and I welcome to my channel.
I am gonna made a 3.7volt battery level indicator. This battery indicator is made with bc548 transistor. It is very easy and simple to make. And it is also useful for people who don't have multimeter or you can also make this circuit..
Component needed are;-
1)bc548 transistor
2)10k resistor
3)1N1007 dioide
4)1.2k resistor
5)3mm led *2
About circuit;-
Connect the 10k resistor with emitter point of the transistor, join base point to 10k resistor with jumper wire, connect to collector point to 1.2k resistor, and connect led p+ to collector and negative point to base of transistor, connect diode p+to the base of transistor and connect another led p+ with 1.2k resisor and led's negative to diode negative.
