Homemade Battery Monitor Using AVR Using Atmega

 

 

 

 

 

 

 

 

 

 

 

 

I want to share my experiment with voltage divider, ADC and AVR
Homemade battery monitor using AVR
It’s pretty simple the sensor are only two resistors and zener diode with capasitor, I don’t buy them, I’ve found it in my box.
We can use it for monitoring our car battery voltage.

Step 1: The Part I Used

 

 

 

 

 

 

 

 

 

 

 

 

1.ATMEGA128
2.10K and 56K resistors as a voltage divider
3. 5V1 Zener diode
4.  1uF Caps,
5. 16×2 LCD
6.    3 wires to connect the sensor into ADC

Let’s continue to the code
