Pi-ject Time

I've explored my options and decided that I would like to do a project involving a calendar for the Computer Science Department at Delaware State University. There is a TV in the lounge that is not being used so I had the idea to use it has a calendar so that the students may stay up to date. I may even have a slide show of announcements that are relevant to the culture of the students that hang in the lounge. I will need to download some software onto the Pi for this to happen. I will update my blog as I begin this process.

Trials and Tri-Pi-lations


Today I realized I was using the wrong resistors WOOPS so my lights in previous videos were dimmer than they're supposed to be. I was using the 220 ohm resistors when I should have been using the 300 ohm Here is a video with the correct resistors. Notice that only the yellow light is dimmer than the rest. This is my light show. I will tweak it to blink to the tune of Twinkle Twinkle Little Star but I want to focus on my project for the year so here is my final LED light show. Thank you for watching!

Second Day Pi

Today we were in class and worked further more on a light show using the raspberry pi. I managed to get the lights to do some cool things. The video below is an example of my lights simply blinking on and off three times. I will later insert the code for this particular code but there are better things to come!

Slice of Pi

Today was the first day I opened my Raspberry Pi. Upon my first time opening it I was given the task of making an LED turn on via a bread board and command lines. The positive side of the LED connected to GPIO2 and the negative side connected to a 220 ohm resistor which was connected to the GND (ground) of the bread board. The command lines needed to initiate the task are as follows:

sudo su

echo 2 > /sys/class/gpio/export

cd /sys/class/gpio/gpio2

echo out > direction


Those commands told the pi where the LED was connected on the breadboard. the code needed to turn the light on is: echo 1 > value. The code needed to turn the light off is: echo 0> value. To see where the current value is: cat value


I am next going to see whether or not it is possible to control my pi via my Macbook Pro with the El Capitan OS.
