There are many reasons to build your own Arduino circuit on a protoboard or a custom-designed printed circuit board. At the heart of the Arduino platform is an AVR microcontroller, in usual way you ...

“The programming and debug pins on any MCU are also shared with other functions of the chip ... and works with the ICSP (in-circuit serial programming) interface. Once the PDID configuration bit is ...

Whether you’ve never touched a microcontroller before ... we’ll look at several different programming options, then build and program a test circuit. This is not the only option.

insert the microcontroller in the programmer, apply power and type make writeflash. This generates the hex file used by AVRDUDE and writes its contents to the chip's Flash program memory. Figure 4.

The only downside is that you’ve got to manually wire it up to your microcontroller of choice. Unless you’re [Roey Benamotz], that is. He’s recently created the LEan Mean Programming mAchine ...
