In this article we will present one possible method to put a bootloader into a virgin Arduino's ATMega 328P.
We'll utilize :

  • Arduino 2009 board with power supply (via USB from PC or external);
  • A virgin ATMega 328P micro controller;
  • 4 wires.

Sensoristic applying field is fascinating, and sometimes sounds magic or something common people cannot approach immediately.

Our body is full of sensors (like ears) able to capture vibrations or other stuff: so you natively have parameters which to confront and start with.

One classical example to take confidence  in electronic circuits is related to charging/discharging capacitors (symbol: C).

These components are able to catch electrical charges and to keep them for a long time; theoretically for an infinite one, but this is impossible, first of all because of Joule effect (heat dissipation to the ambient with slow progressive energy loosing).
