Introduction: Standalone Arduino

After getting into arduino it can get very costly to get arduino boards for projects and so here is a tutorial how to get to next level by getting all parts from board to a circuit significantly reducing cost.

Step 1: Get an Atmega328 With Arduino Uno Boot Loader on It.

You can get hold on them from aliexpress or banggoog for cheap like 2 dollars each with. bootloader or for 1 dollar without bootloader.

Step 2: Other Parts

Things needed are :
1 Atmega328p with arduino uno bootloader
2 16.000 mhz crystal oscillator
3 2 * 22 or 27 picofarad load capacitors
4 0.1 microfarad capacitor
5 6 pin ttl programmer
6 jumper cables
7 breadboard
8 led

Step 3: Connections

Connections :
pin1 to 0.1 micrograms capacitor
pin 9 and 10 to crystal oscillator
load capacitors if 22 pf from pins 9 and 10 to pin 8
positive end of led to pin 19 and negative to pin 22.

Step 4: Connections to Programmer

Connections :
dtr to 0.1 microfarad capacitor's empty end.
vcc to pin 7
gnd to pin 8
rx to pin 3
tx to pin 2

Step 5: Uploading Sketch

Hook the programmer to pc and program from arduino ide as arduino uno

Nice. Could you get by without the crystal and just use the in built 8mhz (or whatever it is) oscillator in the atmega?

I will soon post that instructable too.

Nice. Takes up a lot less space than the whole arduino board.
