Turning on an LED with your Raspberry Pi''s GPIO Pins | …

2015/6/11· The circuit consists of a power supply (the Raspberry Pi), an LED that lights when the power is applied, and a resistor to limit the current that can flow through the circuit. You will be using one of the ‘ground’ (GND) pins to act like the ‘negative’ or 0 volt ends of a battery.

How to Use a LCD Screen/Display with Raspberry Pi - …

2017/6/18· Screens designed to work with the GPIO headers should have installation instructions for their drivers, however, you need to be careful that you buy one that is compatible with your model Pi. For example, a HAT designed to work with the older, 26-pin Raspberry Pi may not work with the newer B+ models which have a 40-pin header, and vice versa.

How do I supply power through the GPIO? - Raspberry Pi …

First of all, using 5V GPIO pin you are bypassing input fuse that is on the RPi. This means you have no protection in case you make some short cut etc. So if you do, a lot of current (depending on how much you power supply can supply) can flow through your Pi
