Let's Make Our Own Arduino!

Arduino standalone, however it does not quite mean when we translate it into Turkish, we can call it independent arduino, breadboarda, copper crowbar, even draw our own diagram and press copper plate.

arduino standalone Arduino may take up a lot of space for our projects on its own, and sometimes we don't even need unnecessary pinouts and pinouts, so we can save space and make more sensible placements. In short, there can be many reasons for standalone arduino, for me this experience began in 2013 when I wanted to reassess rather than throw away the burning arduino of the LM7805 regulator. arduino standalone

Here the AMS1117 was used for 5V regulation, the LM7805 was used in the model I used, they have exactly the same purpose and duty, there is not much difference between them.

At first I thought the problem was caused by ATmega328P, so I learned that I could try it with a "standalone" system, which required a programmer, and that's when I got a programmer rather than change the regulator, and I got new experiences in a long way rather than going the short way and avoiding experience. Before further ado, I'm going into the content; Materials to Use; Atmega328P x1 16Mhz Crystal oscillator x1 22pF Capacitor x2 LED x1 220 Ohm x2 Breadboard x1 We also need a programmer to install our code, for this we can do it with Arduino or USB to TTL, i.e. serial connection circuit, we also need a software that we can use arduino IDE from within. This will be the final version of our circuit with small touches, in addition to the above parts, a button was placed between pin1 and gnd for 5V regulator and reset, where resistance on the other leg of the button was used as a pull-up. arduino standalone

And now to our connections;

We're putting our regulator in place for power and gnd connections. Regulator information is available in more detail below, but it indicates that the input range must be in the range of 5V and 15V otherwise our high voltage integrated may burn and at low voltage it will not work stable.

We place our LED and 200-ohm resistance. That way, we can make sure our power supply works.

We also place our ATmega328P integration and make our cable connections as follows, in addition to preventing image pollution with the upper and lower channels of the breadboard. arduino standalone

  • Pin 7 – Vcc –
  • Pin 8 – GND
  • Pin 22 – GND
  • Pin 21 – AREF – Analog reference pin
  • Feed voltage for Pin 20AVccADC converters.

In the 16 MHz oscilator, we connect the pin 9 and 10, followed by two 22 pF capacitors directly to GND.

Then, when we install new codes, we put a button between pin1 and gnd to reset so that we can reset them when necessary.

We add an LED to pin 13, our SCL (Serial Clock) pin, which is a very useful method for program testing.
