My name is Carlo and I am a 58-year-old 'young' man who wants to learn how to use Arduino.
Sorry if I ask stupid questions and thank you in advance for your answers...
...and now it's time to start studying...
@carlinetor Welcome to the forum Carlo. A few good resources are the Arduino.cc web site, and some documents at https://docs.arduino.cc/learn/ , https://www.arduino.cc/reference/en/ , https://bityl.co/OnGG
Also, some other websites that we often reference is the randomnerdstutorials and the Swiss guy (YouTuber)
It will help if you first get a grasp of stuff like number representation (especially HEX and BIN), boolean logic, state machine theory and the general specs of whatever boards you plan to use (available on the various company websites and known as datasheets) here is the Arduino UNO as an example https://store-usa.arduino.cc/products/arduino-uno-rev3?selectedStore=us . Keep in mind we use the Arduino IDE for more than just Arduinos, it includes espressif boards like esp8266 and family, esp32 and family, and now the Raspberry Pi PICO as well.
Here is my board manager list
First computer 1959. Retired from my own computer company 2004.
Hardware - Expert in 1401, and 360, fairly knowledge in PC plus numerous MPU's and MCU's
Major Languages - Machine language, 360 Macro Assembler, Intel Assembler, PL/I and PL1, Pascal, Basic, C plus numerous job control and scripting languages.
Sure you can learn to be a programmer, it will take the same amount of time for me to learn to be a Doctor.
