Answer 2

Raspberry Pi

3. GPIO and BCM

• The GPIO(general purpose input output) port handles both incoming and outgoing signals.
• Input Port is used to communicate the signals with CPU to switch on or off, which is recieved from switches or sensors.
• BCM refers to the pin by “Broadcom SOC Channel.
• BCM  channel changes as the version numberr changes.
• To prevent the Raspberry pi from damage it is needed to wrire limited number of resistors with GPIO pins.
