* = Prices are the best information from the time this tutorial was written. Next, open the archive and extract the file 'AdaFruit.fzbz' to a convenient spot (I use the Desktop). Parts List / BOM (Bill of Materials) – Excluding Raspberry PI Part The first step is to download the latest version of the Adafruit Fritzing Library from GitHub The easiest way to do that is to click that big nice button up there, otherwise you can also go to the GitHub repository and manually download or clone. If (pirVal = True): # check if the input is HIGH PirVal = GPIO.input(PIR) # read input value Includes practical session for students to draw schematic, write coding and simulate on Raspberry. PirVal = False # we start, assuming no motion detected 3.9K views 2 years ago MALAYSIA Idea sharing on how to teach Raspberry Pi through online. PirState = False # we start, assuming no motion detected ALL OF THIS SHOULD CONNECT THROUGH THE RASPBERRY PI. This requires the AdafruitFritzing library. The wiring should reflect the function of the DHT11 sensor and the PIR sensor being used to turn on.

Using the Adafruit Raspberry Pi Cobbler, here’s how I connected the Raspberry Pi GPIO pins to the breadboard and wired up the PIR sensor and LEDĭownload the Fritzing diagram. The way this project works is by sensing motion using a PIR, Passive Infra-Red, sensor. Beginner Protip 5 minutes 4,106 Things used in this project Story Fritzing is a virtual circuit creator app, that allows you to make virtual circuits freely.

I still use output to blink an LED, but now I also use input to decide when to blink the LED. Of course, the first project was to blink an LED!įor my second project, I decided to expand on the first. I purchased my first Raspberry Pi and since my interest is more in line with interacting with the physical than just having a small computer, I needed a second project. I have been using the Arduino for a few years now and recently curiosity got the better of me with the excitement around the Raspberry Pi.
