When someone talking about the ATmega microcontroller, most of you here must be very interested on it, as it’s one of the most popular microcontrollers that have been widely used, especially in electrical and electronic field!
By the way, do you have any chances develop or create SI Prog before? Well, if you haven’t, then you may want to test it out by your own, coz today you’re about to create a simplification LancOs’s SI Prog aka the Intelligent Serial Port Programmer!
The whole project won’t cost you too much, as you can use either ATmega8 or ATmega 32 as the main component. Oh, if your AVRs reset pin in datasheet have a bar on the name of it (Reset or has a circle outside the pin of it), then this programmer is the most suitable for you here.
One more thing that you should take note when you’re dealing with this project! Always ensure that the emitter and base of the BC547 IC is working properly, for the purpose you can use your multimeter in diode mode and check it. If you have detected an approximately 0.7 Volt drop occur between base and emitter, then it will work fine here!
