Don't confuse this with the Pi Zero — the two are not related. I found these awesome Raspberry Pi pinout diagrams by Pighixxx at Flickr. A Raspberry Pi Zero with smaller size and reduced input/output (I/O) and general-purpose input/output (GPIO) capabilities was released in November 2015 for US$5. The choice of GPIO 17 was simply because I considered it less likely to conflict with other peripherals likely to be in use. 4) Multiroom audio for under £100. 3V to the actuators from its GPIO pins. So, I would recommend you to first have a look at LED Blinking with Raspberry Pi 3 in which we have designed this simple project and then check How to Create GUI in Raspberry Pi 3, where we have controlled that LED digitally with GUI. Introduction.
