Joy of Programming

Programming brings me joy. Whenever I am struggling and making mistakes, I turn them into integers. Ever make mistakes in life? Let’s make them integers. Yeah, they’re integers now. Bob Ross (paraphrased) Sometimes I struggle so much with a programming task that I lose sight of the joy. I get deep into a prideful fugue, […]
Variables in JavaScript

A variable is a named container that can hold a single value. The value can be changed at any time. Declaration In order to use a variable in our JavaScript code, we must first declare it. Use the var keyword to declare a variable, followed by some whitespace, and then the variable name (x), finishing […]
Servo Motors on Three Axes

If we are designing a robot arm, we need it to be able to rotate freely on three axes; X, Y, and Z. This lesson covers connecting three servo motors to an Arduino UNO board, as well as controlling them with C++ code, using the Arduino IDE to deply the program over USB. Servo Motors […]
Servo Motors

In this lesson, we will connect a servo motor (and supporting components) to an Arduino UNO board and program the servo motor in C++ with the Arduino IDE. Circuit Diagram The components needed to complete this circuit: C++ Code
Solve a Maze

When we solve a maze, many of the techniques we utilize are far beyond the capability of even an advanced robot. For example, we can take a look and try out possible pathways without having to start physically or virtually moving through the maze. But what if we have no view to utilize, where all […]
Draw a Maze

Not just for mice anymore! One way to design, program, and test robots: Teach them to solve a maze. Before we can solve a maze, however, we need to design a tool that creates a single-solution maze. The best way to create and solve a maze is in software. Even when a physical robot is […]
