Week 8: Embedded Programming

this weeks task, we had to use our programmer to program a circuit with an LED. As this class was in the same time frame as design dialogue preparation, I decided to simple circuit that applies what I learnt during the local class

From Ideas to code

In the Local class, we learnt that flow charts help ideate ideas into a working circuit. Here we learnt in Arduino, statments manage how the program reacts

Some notes on Microcontrollers:

Mircocontroller -> mostly single-purpose, programmable

Microprocessors -> able to run OS, more multi-pupose, programmable

Input Outpu programmins: The microcontroller will interface with the outter world with its PINs. Pins can serve to receive information, i.e. inputs, or actuate, i.e. outputs

We can use control flow statements to manage how our program reacts to different inputs and actuates on the outputs.

Blink an LED project

For my project, I used an Arduino UNO ( As I do not own an ESP32) to blink an LED. On a breadboard I compiled a circuit where the LED should turn on for a second and off for a second in a loop.

Parts Needed:

(1) Arduino Uno

(1) USB A-to-B Cable

(1) Breadboard – Half Size

(1) LED 5mm

(1) 220 Ω Resistor

(2) Jumper Wires

Project Code:

this is the diagram of the circuit I wanted to make

This is a screenshot of the arduino circuit code for the LED

Image of components needed for the circuit

Explanation of the code:

void setup() {

pinMode(13, OUTPUT); } -This is the pin connected to the Arduino

void loop()

{

digitalWrite(13, HIGH); - Turn on the LED

delay(1000); -Wait for one second

digitalWrite(13, LOW); -Turn off the LED

delay(1000); -Wait for one second }
