Is it possible to flash the firmware to an arduino nano and then unsolder the atmega328p and insert it into my homemade?

Question

Arduino

The idea is strange in itself, but the dimensions of the arduino nano do not fit in my project. [In fact, the project is only to make the LEDs blink when the sensor is touched in 3 different modes] The presence of a programmer is absent, there is no particular time to wait, other microcontrollers are not available. Is it possible to upload firmware to the nano via the Arduino IDE, pull out the microcontroller itself and insert it into your homemade product?

Answer 1

Can. But you need to keep the binding necessary for mk. Decide on food. Clock source (it can be excluded if you use the built-in micro).

Answer 2

It's possible, but what's the point? A properly wired 328 mega board will be almost the size of a nano. Use your arduino as a programmer, just search "avr programmer for arduino". As kalapanga rightly pointed out , it should be added to support your arduino ide for bare processors. You can use the manual from Guyver , detailed. Your code will most likely fit into tiny13, which is much smaller and requires less strapping.
