Hi @Koepel,

It is originally my circuit, with only one adjustment on the voltage divider.

Atmega328 not Working in Circuit SOLVED!

Hi all! I am making a battery level indicator for my electric four wheeler. It uses 36 volts (3x 12v batteries). I made a circuit of an atmega328 with a 16mhz crystal, 2x 22pf capacitors also for the timing, a 100nf filter capacitor on the input power supply, and a 10k resistor from RST to +5v. Then I added 7 leds with 220 ohm resistors on them on seven different digital pins of the atmega328. Then I added a voltage divider of a 68k ohm and a 10k ohm resistor to read the battery voltage on …
