Demo Video: Raspberry Pi Traffic Lights
Using basic Python code we can program these lights to flash just light traffic lights.
Demo Video: What is a Rasperry Pi?
The Raspberry Pi is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse. It is a capable little device that enables people of all ages to explore computing, and to learn how to program in languages like Scratch and Python. It’s capable of doing everything
Connect Raspberry Pi to DHT11 Temp Humidity Sensor

Get to the Terminal.
Raspberry Pi Install Operating System
To get your device up and running we need to install the Operating System. You can: 1) Use NOOBS, and copy NOOBS to a USB Keyfob and boot the device. This can be problematic when trying to re-install the OS. 2) Download the Raspian image and use RUFUS to burn the image to a USB
Raspberry Pi Commands
Sudo – generally you put sudo in front of everything that requires permissions to run, such as mkdir. sudo raspi-config this will give you a terminal based configuration interface. Very handy when using Putty remotely. Filesystem Commands ls The ls command lists the content of the current directory (or one that is specified). It can
