4. Embedded programming¶
This week I was trying to learn about microcontrollers and how to program it.
Group Assignment¶
Our task in groups was to search about a certain microcontroller and learn about its specs, then every group share what they found with others.
Our microcontroller was “Adafruit Feather BlueFruit Sense nRF52840”
Indivisual Task¶
After taking a glance about microcontrollers everyone took a microcontroller and tried to program it using some codes
We used Arduino IDE to write codes
First of all you need to identify the microcontroller for the program like this
-This is the first screen of the Arduino IDE:
-From the top choose:
-Finally find your microcontroller
First Try¶
We used a written code to understand codes writing as illustrated:
from “File” tap choose “Examples”, then “Basics” and finally “Blink”
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(LED_BUILTIN, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
Result video
Second Try¶
Trying to make some changes in the code by changing the time
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(LED_BUILTIN, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(200); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
Result video
Third Try¶
Trying to make the LED turn on and off by a random time between 25 and 200 millisecond
int randNumber;
void setup() {
pinMode(LED_BUILTIN, OUTPUT);
}
void loop() {
digitalWrite(LED_BUILTIN, !digitalRead(LED_BUILTIN)); // turn the LED on/off
randNumber = random(25, 200);
delay(randNumber); // wait
}
Result video
