Keypad Project with Raspberry PI About the Project: Here is one of my favorites. This post is a step by step of how to set up a keypad while using Python on the Raspberry PI to perform mathematical computations. We will be using Python programming because it is compatible with the Raspberry PI. This project was inspired by my first project, which accomplishes the same thing but with C++ programming and Arduino. Make sure to go check that one out too! It will give you different view on the same project. I decided that I wanted to do this project on the Raspberry PI as well because I wanted to practice Python programming. I hope this is helpful! **Make sure to check out the previous two posts to set up your Raspberry if it is not already set up** Additional Material Needed: ( Apart from the material needed to connect the Raspberry PI to the monitor: refer to last post): Wires Keypad Make sure that the pins are only on one side of the wire! (aka: male-female jumper cables)   **It is ...

Connecting a Raspberry PI using a VNC Because there are not a lot of connections needed when using the a VNC, I found this to be very helpful when coding with Raspberry PI and thought I would share! What is a VNC? VNC stands for Virtual Network Computing, and it is a way for people to use their computers, which are are much easier to transport compared to monitors. It works the same as using the monitor and allows an user to connect to the Raspberry to project what would normally be seen on the monitor onto the computer. It works the same as using the monitor.  Requirements: In order to connect to a VNC, you will have to be able to navigate the home screen on the Raspberry PI. I will be using my set up from the last blog to demonstrate.  Step by Step for VNC: 1) First, we have to ensure that the VNC viewer is installed on your device. There are many websites that allow you to do this but here is the one that I used from the official realvnc website. realvnc.com: Install the VN...

Connecting the Raspberry PI  This is just a little something I learned about the Raspberry PI when I started working with it and wanted to share it with you guys! Materials Needed: *: needs a USB pin to connect Raspberry PI Mouse* Monitor Keyboard* HDMI cable Power Supply Cable Step by Step(for the connections): 1) Connect an HDMI cable to the Raspberry PI and monitor. There are HDMI ports on both the monitor and PI, and the HDMI port on the Raspberry PI is located at the bottom of the device.  2)  Use the power supply cable to turn the Raspberry PI on. To do this, connect the power supply cord by first plugging it into the wall and then plugging the other side into the port at the bottom of the PI(to the left of the HDMI port).  3) Connect the mouse and the keyboard by plugging their pins into two of the four USB ports that are located at the top right of the Raspberry PI. 

Basics of the Raspberry PI  What is a Raspberry PI? My Raspberry PI: Model three and runs the Raspbian operating system The Raspberry PI is computer that is the size of a card. It has one sim card sized chip that controls the whole computer. It was created in Europe by multiple founders, and it is a British manufactured product. There are many ways to use this computer, the most common being connecting it to a monitor while using a keyboard and mouse.  Way to figure out what version is being run: There are different codes that can be run to determine which version is being run on your Raspberry.  The codes are listed below:  Check which version of the Raspberry PI you have Operating systems The Raspberry PI can run a multitude of operating systems such as Raspbian (a "water down" form of the Linux operating system ), Lakka, OMSC, Windows IoT Core(from Windows), and more. These operating systems can be installed onto the Raspberry PI itself, allowing the users to...

Keypad Calculator Project: About this Project: This is the step by step process on how to set up the Arduino Keypad and then using it to perform the basic mathematical computations. I decided that I wanted to do this project because I knew I wanted to try something new with programming. The Arduino was an excellent way to to do this because it used a software that I was not accustomed, making me take hours to learn and understand this program(this was the fun part). I wanted to use my creativity to make something that was not made before, and I came up with this. I will be explaining how I set up my keypad using all of material listed below, along with the software and code required to accomplish this. The code will provide the computational properties of this device, and this is a fun way to incorporate a calculator into an Arduino project. I hope you enjoy!!  Materials Needed: Wires Arduino UNO board USB cable Keypad A few pairs of wires which come with the Arduino kit. The pins ...
