Entry 5: Arduino

This week, we explored the concept of physical computing. We learned about various things regarding the same including the identification of physical components (like water sensors, wifi, microcontroller, and many more), transducers (sensors and actuators), and working with the Arduino stimulator.

Transducers are devices that help in converting one form of energy to another. Sensors are used to convert physical action to electrical signals (like microphones) while Actuators convert electrical signals to physical action (like speakers).

Working with the Arduino stimulator was exciting but what was more exciting was when we physically implemented it using the Arduino Starter Kit. It was a thrilling experience to see our code visually through the microcontroller.

This was the code used to blink pin 13 on the board:

Below you can find the stimulator:

And here's the actual physical implementation of the code for blinking the builtin LED light (pin 13):

Then, the code was changed to blink three different LED lights using the breadboard, LED lights, and resistors.

This code makes three LED lights blink on and off consecutively. The stimulator for the same is as follows:
