How To Use GPIO Pins On Raspberry

Connection of GPIO Pins On Raspberry Pi and LEDs/buttons. There are 8 available GPIO Pins on Raspberry Pi. See connection shown in the diagram. Resistors value can be caculated as this. My 5mm LED’s forward current is around 20mA (might be different to yours), voltage supply from RPi is 3.3V, so the resistor for LED is 3.3 V / 20 mA = 165 …

Computer Laboratory – Raspberry Pi: …

Operating a Simple Switch and LED on the Raspberry Pi. GPIO, as may have been explained in other tutorials, stands for General Purpose Input/Output and a GPIO pin can be set high (taking the value 1) by connecting it to a voltage supply, or set low (taking the value 0) by connecting it to ground. The Raspberry Pi can set the pin to take either …
