Project tested and working perfectly

Yet another project from our Italian friend

Bascom-Avr Compiler

ATMEGA48 DDS Audio Function Generator

Frequency range : 1Hz - 20KHz useful to 100KHz
Resolution : 1Hz
Waveform : Sine, Square, Triangle, Sawtooth
Output level : Adjustable 0 - 5V.p.p.
Square wave open drain output (TTL compatible)
Battery powered

I don't recommend this project for anyone who is NEW to electronics.

ATMEGA48 Fuses configuration:
Spien ON ,Rstdisab OFF, Esave OFF, Ckout OFF, Wdton OFF, Ckdiv OFF,
SelfprgEn OFF, DwEn OFF, Bodlevel = 111 , Cksel = 0111 , Sut = 11

@Michal, that rocket is too heavy for itself and trust is not enough unless afterburners are fed with fuel properly.

Hello sir, is it ok to use 12.000MHz oscillator in IRswitch, because the requirement written in the post is 11.059MHz. And i use PIC1018 as an Ir receiver

Hello sir, your blog is kind of helpful for us especially students. May I know do you have the coding for decimal to binary using proteus 8. My mini project is about to convert decimal to binary just like a calculator. The output is LCD. A bit confusing is the decimal to binary coding on proteus 8. pls help thanks.
