The Arduino Uno is a digital device, but it has an analog-to-digital converter (ADC) to allow us to probe the analog signals that permeating our analog world. The ADC is a 10-bit device that can map an analog signal consisting of a voltage ranging from 0 to 5 volts to a decimal value between 0

In Excel, you can apply a line-of-best fit to any scatterplot. The equation for the fit can be displayed but the standard error of the slope and y-intercept are not give. To find these statistics, use the LINEST function instead. The LINEST function performs linear regression calculations and is an array function, which means that

Although it creates bulky AVI files, MATLAB can relatively easily make movies of animated figures. The code below prototypes how this is done. % define the number of frames in your movie numberOfFrames = 1200; % use a loop to generate frames of the movie for ii = 1:numberOfFrames % insert code to update data
