First Codes — Code I

We need to flash an LED. Let’s say I want to flash an LED connected to Pin 3; This is our Hello World!

Blinking LED with the Arduino running autonomously in 9 volts (J3 Resistance wheel?)

Code II

Now the LED is under your command! Push the button to Light it up!

Code III

Let’s add a potentiometer and send the analog signal to control the intensity of the LED, called PWM. Do not be scared, the names we see later, see how it works and that’s it!

Code IV

With the same analog signal of the previous code, we will control the Servo; just add the library:)

Code V

In this last code, the button and the potentiometer work together …

Now, how to design a product. We followed Jeremy Blum’s primer; see translations.

Here is an infographic from Jeremy Blum translated into Portuguese and aimed to guide you in creating a Minimum Viable Product (MVP):

Conclusion (AFTER THE CLASS…)

The initial difficulty of the children seems to me at first to have the vision of the whole. I think everything in electronics comes down to this figure:

Input — processing — output or more specifically for hobbyists on duty: sensors — controller — actuators; have the vision of the whole demand sleep on the project and wake up thinking, rethinking and understanding slowly all the concepts involved and systems theory, above; )

Remember, do not give up! Sometimes we plan more than we try. Know that when we put our hand to work we have to work hard! nothing comes for free…
