What's the orientation of this pinout? Pinout depicts pin 1 in the top left corner. Pin 1 is the only pin with a square solder pad, which may only be visible from the underside of your Pi. If you orient your Pi such that you are looking at the top with the GPIO on the right and HDMI port (s) on the left, your orientation will match.

It appears the default output once setting the pin to be output is for the value to be high. Based on the docs, you can use the parameter initial=GPIO.HIGH to set the initial value. GPIO.setup (channel1, GPIO.OUT,initial=GPIO.HIGH) The code above sets the initial value to low according to the OP. Not sure why this happens.

The concept is simple: the LED is an output of pin 4 and the button is an input of pin 22. The button circuit has a pull-down resistor. Pin 22 will be pulled down to zero through the 10K resistor when the button is inactive. When it gets pressed, the 3.3V power from the Raspberry Pi goes into the pin 22 input, bypassing the 10K resistor.

The early models used a 26-pin connector, starting with the Raspberry Pi 2 this was expanded to 40 pins. Both the Zero and Zero W use this 40-pin standard. The GPIO connector allows you to expand your Pi by attaching additional circuit boards known as HAT's (Hardware At Top). There are 4 PWM pins on the Raspberry Pi, but each pair of the 4 pins is sharing one PWM resource. GPIO12 and GPIO 18 are sharing one PWM channel while GPIO 13 and GPIO 19 are sharing on the other one. This means that there are only 2 unique/controllable PWM channels on the pi. You can checkout Pinout.xyz to know more about the Raspberry Pi's.
