Learn to build buttons that will translate numbers to binary.
In this project, students will explore binary code, a foundational part of computing. Students will try to “speak” a few numbers in machine language, just as computers do.

Troubleshooting Tips
Are you not receiving any inputs from the button presses?
Ensure that you’ve plugged the wires into the right GPIO. Look at the Digital View to see which pin you’re affecting.
What is binary?
Binary describes a numbering scheme with only two possible values for each digit – 0 or 1 –. It is the basis for all binary code used in computing systems

Term Glossary
Circuit A conductive path for the flow of current or electricity.
Power The current or flow of electric charge and voltage.
Microcontroller An integrated circuit containing a microprocessor with memory and associated circuits.
Variables A value that can change depending on conditions or information passed to the program. A storage location with a symbolic name used to keep track of a value that can change while a program is running (similar concept to using X and Y in an algebraic equation). Variables are not only numbers; they can also hold text, including whole sentences (strings) or logical values (true or false).
Input Device A hardware device that sends data to a computer, allowing interaction and control.
Output Device A piece of hardware that converts information into a form humans can sense and understand.
