How are the pins on a Raspberry Pi connected?
Don’t plug in the Raspberry Pi power cable for the moment. Before going further, you need to understand how a breadboard works. Each hole is a pin you can use to plug something. On the edges of the board, there are two lines: Each port is connected with all the pins from the same line.
Are there GPIO pins in the Raspberry Pi 3?
Whether it’s the Raspberry Pi 3, 4 or the tiny Raspberry Pi Zero, GPIO pins have always been a staple feature of our favourite single board computer (SBC), the RPi. However, do you know about its functionality and how to use it to create real world projects?

Here are the useful specifications to know: Model Format Ports Memory A Standard 1x USB HDMI 256 MB A+ Compact 1x USB HDMI 256 / 512 MB B Compact Ethernet 2x USB HDMI 256 / 512 MB B+ Standard Ethernet 4x USB HDMI 256 / 512 MB
Where is the VDD pin on a Raspberry Pi?
To power the MCP23017, connect the VDD pin to +5V voltage rail, and the VSS pin to the ground rail. Connect the SCL and SDA pins on the MCP23017 to the I2C pins on the Raspberry Pi hardware. Set the I2C device address of the MCP23017 to ‘0x20’ by grounding the A0, A1, A2 pins. Connect the RESET pin to the +5V voltage rail.
