If you ever have a project using two or more Arduinos, it's likely you'll want them to work together.

Say for example you have one Arduino connected to an LCD shield, and another Arduino controlling an LED matrix. You want both to...

👉 Learn how to graph quadratics in standard form. A quadratic equation is an equation whose highest exponent in the variable(s) is 2. To graph a quadratic equation, we make use of a table of values and the fact that the graph of a...

A walk through of the Arduino IDE, the software used to program the Arduino.

Have you ever had your internet go down? You call the service provider and the first thing they say is that you must unplug your modem and wireless router, turn off your computer, and scratch your keyboard 7 times with a chickens...

Attention is the gasoline of the care of learning. What are you doing to win over that buy in and shift student's consciousness to your class? Here are three simple ideas for beginning that process.

7 Arduino Tips for New Programmers

Learn how to graph a horizontal parabola. A parabola is the shape of the graph of a quadratic equation. A parabola is said to be horizontal if it opens to the left or opens to the right. A horizontal parabola results from a quadratic...

👉 Learn how to convert angles from radians to degrees. Recall that pi radians is equivalent to 180 degrees. Thus, when given an angle in radians, to convert the angle to degrees we multiply the given angle radians by the ratio 180/pi.

👉 Learn how to sketch angles in terms of pi. An angle is the figure formed by two rays sharing the same endpoint. Angle is measured in radians or in degrees. One complete revolution about a point is equivalent to 2pi radians and 360...

This is a tutorial on how to create a Hexham cam using Onshape software. The video provides step-by-step instructions on sketching, dimensioning, extruding and filleting the cam. It also includes tips on renaming the part and editing the...

In this video, the speaker gives a lecture about sketching quadratics where the value of A is equal to 1. They explain the general shape of a quadratic and how completing the square can help find the turning points and line of symmetry....

👉 Learn how to find the reference angle of a given angle. The reference angle is the acute angle formed by the terminal side of an angle and the x-axis. To find the reference angle, we determine the quadrant on which the given angle lies...

Did you know in the Arduino IDE that you can organize your code using different tabs? In this lesson, you’re gonna learn how to add these tabs, how they get organized in the Arduino sketch folder and how to use them in order to better...

Understanding how the Arduino IDE sets up its file directory system can spare you some confusion when it comes to saving, organizing and opening your Arduino sketches (or sketches you have downloaded from the...

👉 Learn how to find the reference angle of a given angle. The reference angle is the acute angle formed by the terminal side of an angle and the x-axis. To find the reference angle, we determine the quadrant on which the given angle lies...

In this lesson, students learn how to sketch the graph of higher degree polynomial functions by finding the x-intercepts and determining the end behavior. They are guided through the process of setting the polynomial equal to zero,...

Self-portraits are images that look outward and inward, revealing what we truly feel inside and displaying our personalities and interests.



In this activity, children aged 8-11 will create a hand-drawn selfie to explore...

👉 Learn about the special right triangles. A special right triangle is a right triangle having angles of 30, 60, 90, or 45, 45, 90. Knowledge of the ratio of the length of sides of a special right triangle enables us to solve for any...

👉 Learn how to find the midpoint between two points. The midpoint between two points is the point halfway the line joining two given points in the coordinate plane. To find the midpoint between two points we add the x-coordinates of the...
