Hi everyone, It's me Balsuryana!. I'am back with some electronics projects! In this projects, i will show you how to make a Battery Level Indicator.
I got this idea because i need this tools for indicate my powerbank battery level, so i made this tools. No more talking, LET'S MAKE IT!
Step 1: What You Will Need?
- HT3786 (LCD drive power detection)
- Battery level LCD (6 legs LCD) (Image 2 and 3)
- 2 Ceramics capacitor (capacitor code: 104)
- 220 uf, 10v Capacitor
- Some cables
- Soldering iron
Step 2: The Circuits
This is the circuits, you just follow this circuit. Please click the image for zoom the image and more visible.
- C1 = 220 uf
- C2 = Ceramic capacitor
- C3 = Ceramic capacitor
Step 3: Solder the Circuits
Before soldering, you can follow the circuits using breadboard, just insert the Legs to the breadboard, and you can modification the circuits. If you want to solder the circuits, you can use perfboard or you can make the pcb.
If you solder it without anything, it's look like image! :)
Step 4: Let's Test It
If you finish solder your circuits, connect the negative and positive input to battery. This tools can turn on using less than 3 Volts. You can add resistor to the positive input, so you can use more voltage from battery to indentification more voltage battery level.
And thats it! this instructables is finish!
