Picture of the day

Could DSP produce some sort of modern art on some occasion ? Do you want to reproduce that ? Well, here is the recipe … Get a function generator and set the signal pattern to ramp, sweep frequencies from 80 to 90 Hz with 0.1 Hz steps every second. Connect the output to PlainDSP*¬†and starting […]

Alternate IDE (Part 2)

Part 1, 2 Well Notepad++ is really my editor of choice for coding Arduino. Although I am aware of many other powerful editors, I like the style as well as the price (It is free!). Anyway, I felt like Notepad++ was lacking something handy available elsewhere: running external applications. As my first attempts to use […]

DC motors (Part 3)

Part 1, 2, 3 Now that we managed to get rid of (most of) the spike generated by the opening the supply line of the motor, let’s look at this plateau which happens just after the spike. From the pictures in the previous post, we have been able to observe that the voltage of this […]

(Very) serious games

From my primary school in the 60’s, I remember that we flew hundreds of paper planes in the school yard. Depending upon the way paper was folded, these planes would be fast or fly long distance or be able to perform some sorts of acrobatics figures (Mostly unexpected I must say). At the same time […]

DC motors (Part 2)

Part 1, 2, 3 Time for code ! Let’s write a few lines of trivial code in order to drive our controller (Check previous post). You probably heard about the analogWrite() function which is very convenient for generating PWM. Well, we will not use it ! Is it because it is too easy ? It […]
