On this project 3.7 Volts Battery Low and Full Level Indicator Circuit, we’re going to make a very simple Battery degree Indicator. This Indicator Circuit Is For 3.7/ Volts Indicator. We have Designed This Circuit With Few additives At home With easily available additives. Those components Can either Be gathered From An vintage Circuit Or can be purchased From An Electronics store effortlessly.
3.7v Battery low complete indicator
- Transistor – BC547 X1
- Resistor – 1K X2
- Resistor – 220 Ohm X3
- PN-Junction Diode – 1N4007 X1
- LED – 3V X2 (red For Low rate Indication And green For full charge Indication)
- Battery – three.7V And 3V
First of all, join 1K Resistor To Base And Emitter Pin Of The Transistor As proven in the picture Given underneath.
3.7 volts battery indicator
In second forestall Solder 220-Ohm Resistor To The Collector Pin Of The Transistor As proven in the photo.
3.7v battery degree indicator
On this Step connect 1 Kilo-Ohm Resistor With the second factor Of The 220-Ohm Resistor.
Three.7 v battery low full indicator
In Step 4 join Diode IN4007 With the base factor Of Transistor As we have linked within the photograph Given under. Join The Cathode point Of Diode With the base factor Of The Transistor.
Three.7 V battery complete low indicator
Connect – point Of green Led With Diode – point And +Ve factor Of Led green Led With 1k Resistor As proven below.
Three.7v battery level indicator
Solder – point Of purple brought about -Ve factor Of The Diode And + factor Of pink Led With Collector point Of The Transistor As we’ve proven inside the Diagram Given underneath.
3.7V battery stage indicator
Our Circuit Has Been completed Now We take a look at It through Connecting Battery. Connect +Ve Of 3.7 Volts Battery To +Ve point Of inexperienced LED And – point Of 3.7V Battery To Emitter factor Of The Transistor As we’ve related inside the Circuit Given below.
