How do I access UART on Raspberry Pi?
To connect the Raspberry Pi to a PC via UART, you will need a USB Serial Cable that supports 3.3V. As seen on the image above, this cable has four female wires that can be plugged into the Raspberry Pi. The red wire is to be connected to +5V, black wire to GND, green wire to TXD and white wire to RXD.
How do I connect my Raspberry Pi to my laptop?

How many ADC pins does Raspberry Pi 4 have?
Why we need an ADC Analog inputs are handy because many sensors are analog outputs, so we need a way to make the Pi analog-friendly. We’ll do that by wiring up an MCP3008 chip to it. The MCP3008 acts like a “bridge” between digital and analog. It has 8 analog inputs and the Pi can query it using 4 digital pins.
Where are the DNC pins on the Raspberry Pi 4?
An Introduction to the Raspberry Pi’s Pins The GPIO with the Raspberry Pi is the long block of pins in the upper-left corner of the board. Older models had 26 pins, and current models have 40 pins. You can connect components and other hardware devices to these pins and use code to control what the components do.

What are the logic levels of a RPI port?
The ports use 0V and 3.3 V logic levels, not 0 & +5V TTL levels or the +/-12 V used by RS-232 serial ports found on some older PCs. If you wish to connect one of these, you need a board or adapter to convert the signal levels.
