GPIO Resources

I am new to the Raspberry Pi world and would like to mess around with the GPIO and such.

I am looking for some resources, around the GPIO, breadboard and such. I did a quick thing to get Alexa on my pi and got the leds working, but Amazon did really have an explanation of why I used the pins that I did, as well with some resistors.

Thanks

The web is awash with tutorials on using switches and LEDs with RPis. Have you looked?

I started it, just wondering if any one had any solid go to ones to suggest.

I know that adafruit has a few books too.

TBH, most tutorials are not very good. They are either too advanced or too simplistic. Books are where you probably want to be.

Oh yea, the 40 pin gpio should be the same across all devices. I the rpi2 had fewer pins and those are different. I would read up on what each of the pins does.

The original Pi 1 (A and B) had 26 pins, and a few of them had a different configuration. All models from the Pi 1B+ have had the same 40 pin interface, other than a different UART being used on models with Bluetooth.
