The author Samiuddhin replies: Thank you for taking interest in my article. Yes, you can do this same function with digital IC’s but I designed with MCU based in my interest. The EFY magazine is read by all people from beginners to expert. The circuits published in the DIY section are focused for electronic enthusiast. That’s why this project is concept based and not based on cost effective, small size ..etc.,

couldn’t this project be done without any microcontroller? in my opinion, it looks like to prefer luxury a little bit, right? Because anymore its new habit (or fashion) to convert all analog circuits to programmed digital ones.
Engineering or designing is to do everything more basic, more cheap and more practical. what do you do such this?
