To flash the LED we are going to write and run a Python script. Remember the longer lead on the LED is positive and should be connected to Pin 11. The resistor is there to limit current through the LED and should be sized accordingly depending on your LED to prevent burning it out. The LED and resistor should be connected in series between Pin 11 (GPIO17) and Pin 25 (Ground). If you wish to download Fritzing, it is here. Fritzing is an open-source schematic capture and PCB routing software. I like to make Fritzing schematics of my circuits before building them (Figure 5: Fritzing Schematic). I am using a breadboard to make the circuit feel free to the solder the components together or to make a shield out of a protoboard for your Raspberry Pi. Remove the SD card from your computer and insert it into your Raspberry Pi.įigure 4: NOOBS Installing Raspbian Lite 2) Building the Circuit Make sure you copy all the files within the folder and don’t just copy the folder itself, otherwise NOOBS will not boot. Once NOOBS is installed and your SD card is formatted, you can copy all the extracted NOOBS files to the SD card. You can do this with SD Card Formatter 4.0. If your micro SD card is new you may need to format it. Note: If the micro SD card you purchased has NOOBS pre-installed you can skip this and the next step. NOOBS is an OS installer and is used to install different OSs on your Raspberry Pi. The first step is to download the latest version of NOOBS (New Out Of Box Software) from here. Raspbian is a Linux-based OS and is the supported OS of the Raspberry community. In this tutorial, I will show you how to install the OS Raspbian. Parts and Equipment Neededġ) Setting Up Your Raspberry Pi: Downloading NOOBSĪs I stated in the overview, Raspberry Pis are microcomputers that run an operating system. I will then demonstrate using the GPIO to flash an LED ON and OFF every second.Įstimated Time to Complete: 45min.-1hr. In this tutorial I am going to show you how to set up your Raspberry Pi by booting an OS disk image. The difference between Arduino and Raspberry Pi is Arduinos are microcontroller-based boards while Raspberry Pi boards are microprocessor-based and run an operating system (OS).

The series was founded to promote computer science education around the world. Raspberry Pi is a series of single-board computers used by DIYers, hobbyists, and students.
