Sorry SunnySkyguy, i am new to electronic. But I just follow a tutorial on the internet that they said it work well. So, if this not possible, how should the circuit be?
I try to build my own inverter based on circuit on the internet below :
But when I measure the transformer output it just read about 50V. I use 12 V dr accu for power source.
This is my board and transformer.
I also try to replace the transistor using 2N3055 and MJ2955. But nothing changed, it...
So, i can directly use TTL ? so, where should i connect the TTL pin to the microcontroller ?
or where can I find the tutorial regarding interfacing TTL with microcontroller?
Did you mean test for calibration?
Thanks,

TTL just give us information...
Thanks for respond,
I recently contact the seller for datasheet detail, and he gave me an ADC0809 datasheet from National Semiconductor. i thought it has an internal ADC. So how to use the TTL data?
I just bought CO2 gas sensor with 4 pin (VCC,GND,Digitial Output,Analog Output). But I don't know exactly how to interface it with AVR microcontroller ?
Do i need to connect it to ADC ? or it come with ADC module ? I have attach the picture too.
Thanks for help
Hi! I have a project to read adc data from atmega8535 microcontroller to PC using serial. I use Codevision AVR for programming application.
I have try this code, but it just shown an unknown character like this -> ÿ
#include <mega8535.h>
#include <stdio.h>
#include <delay.h>
#define mode_ADC...
