Convert AVR chip into Arduino with ArrDrownHo

As we all know that arduino is an AVR chip with Arduino bootloader flashed in. So in fact in order to develop Arduino based projects you don’t need an Arduino board with all that magic wrapped around. Anyway single AVR chip isn’t going to work in most cases. You will need a power regulator, programmer header , crystal and several passives to make it work. If you don’t want to spend several bucks for Arduino boar and yet want to have breadboard friendly Arduino, you might consider ArrDrwonHo converter. This is nothing special – just a simple small board that comes on top of AVR chip on breadboard and brings all is necessary to flash and run Arduino programs. ArrDrwonHo brings a power regulator that accepts DC from 7V to 18V. Also here you will find serial pins ready for connecting USB to Serial adapter, ISP programming header, 16MHz crystal, power LED and few passives. PCB is designed to be easily built at home labs with hole through components. It great choice for fast prototyping on low budget.   Continue reading

Build your own minimal Arduino with no solder

Arduino is common open source microcontroller platform that is widely accepted among hobbyists and non electronics professionals. However open source doesn’t mean free – if you want to obtain one there are two ways: purchase a readymade board from supplier like Sparkfun or build one as all plans and schematics are freely distributed. Again why to go through all development process and build exact copy of Arduino board only for some prototyping. You can assemble minimalist Arduino platform on breadboard with few necessary components. Anyway this is only a core Arduino. In order to program you still need an USB to serial FTDI dongle – but this can be separate and not a part of project. Again, this is nothing new and extraordinary as you can always find more Arduino Breadboard projects in the internet. Continue reading
