Freso,if you look for fuse calculator there are a lot of free of them in the net.GOOD LUCK!

A good one :

Capacitance voltage has nothing to deal withe ATMEGA burning.
Few things can burn your chip like a short cut, a too high output current etc.. I would check the resistance between all pins / GND and all pins / VCC. Then, i would check the resistors around the chip.
I had troubles with my first board, the LCD show only black squares and no sound on the buzzer. I spent few weeks on this trouble and never found what was wrong. I made a new board and now it works ?????? Electronic is sometime strange

error

I have a question.
sorry for looking like a fool but an error connect power where the coil is connected.

my question is if you have already made solution or lose if so to return to start.
else that you think are burned with the ATmega328 chip, lf357n, IRF840 or voltage regulators mean L7812 and L7805 to me, I might advise.

I'll upload a picture.
Thanks in advance.

Good wiring :

[sabios]

therefore I said that was a mistake.
and check the L78012 and some diodes and a capacitor and it seems the IRF840 is burned, but the question is whether already been made to lose all the work, since I have no special instrument to make measurements.

and not ATMEGA328 state and LF357n ..

I repeat it was my mistake and I admit something silly.

Thanx.... Not a fuse calculator can you show me a good hex burner that dont change fuses config after burning???

[freso]

Thanx my friend but i am looking for a good hex burner because extrem burner changes fuses after hex butning.

I think i am having similar problems like urs no sound and lcd turns off after i plug the coil .... Wich desine do you advise me to make next time... The one i made is small and you dont have space to solder capacitors in right way... Thanx in advence
