Introduction
Short-term memory allows you to answer difficult questions without preparation, improvise and quickly assess the situation. Previously, it was believed that every person has a certain short-term memory, but recent research in the field of cognitive science and psychology has proved that we can train it.
What is short-term memory and why is it important?
It is a “reservoir” for short-term storage of thoughts and ideas, which we can extract and use to make any decisions at any time.When it is necessary to answer a question without preparation, short-term memory allows you to speak simultaneously and mentally plan subsequent statements. It is also used when we read. To understand the essence of the material, we must remember what we read before and link it with what we read next. In addition, short-term memory helps to ignore unnecessary information, including everything that bothers us. Especially in our time, the ability to fully focus on the task is very important.
Now we all suffer from an overabundance of information, social networks and various kinds of warnings that require attention day and night. The brain has to make a lot of effort to determine what information it should remember and what should be remembered. All this causes anxiety and stress and further reduces memory.
How to make short-term memory work at full capacity
There are two ways.
First, reduce the number of distractions and thus reduce stress levels. This has a positive effect not only on memory, but also on all spheres of life.
But sometimes it’s impossible. We cannot predict when the boss will demand an urgent report from us or when our loved one will get sick. To be honest, we usually like the variety of information that is currently presented on the web.
So, the second option remains-to develop and strengthen short-term memory.
How to strengthen short-term memory
Brain Exercises
In particular, the so-called “double n-back problem”. During this exercise, you train your short-term memory by tracking a series of images and discovering that a certain image appeared earlier.
Studies have confirmed that such exercises help strengthen short-term memory, in particular, scientists such as Jackie Au, Ellen Sheehan, Nancy Tsai. But if all the exercises are unstable, it will not help. Short-term memory, like our muscles, requires regular training. Researchers recommend allocating 25 minutes a day for this.
These notes are taken from an article by foreign scientists
Other factors are also prescribed, In short, everything affects our sleep, sports, proper nutrition. What suits us for the game we are doing in this project is just an exercise, so we attach importance to this exercise.
So, we have LEDs in four different colors and buttons in these colors
At the beginning of the first game, the LEDs should light up four times, no matter in what order. Then we have to click and repeat the buttons of the same color. If we find the right one, we produce a sound that indicates that we have moved to the next level through the active buzzer, and if we find the wrong one, we produce a sound that indicates that we have lost. With each correct earnings, the number of fires increases, i.e. with a four-fold combustion after a five-fold combustion, the same thing repeats after six.
Practical part of the work
Now let’s start implementing our game
First, open the Arduino IDE, if not installed, install it by link
after opening the platform for writing code, click the Tools button at the top
Then select the port
The code will not be sent to Arduino if the Port is not selected
The arduino must be connected to the computer via a blue cable
In the figure below, we connected the buttons and LEDs to the arduino board
Connect also
Now, when the buttons are pressed, we light the corresponding LED.
To do this, you need to run the code below
Step 1 Write this code on Arduino IDE or copy
then click on the button listed below
#define redbtn 3
#define yellowbtn 4
#define bluebtn 5
#define whitebtn 6
#define redled 9
#define yellowled 10
#define blueled 11
#define whiteled 12
void setup(){
Serial.begin(9600);
pinMode(redled,OUTPUT);
pinMode(yellowled,OUTPUT);
pinMode(blueled,OUTPUT);
pinMode(whiteled,OUTPUT);
pinMode(whitebtn,INPUT_PULLUP);
pinMode(bluebtn,INPUT_PULLUP);
pinMode(yellowbtn,INPUT_PULLUP);
pinMode(redbtn,INPUT_PULLUP);
}
void loop(){
if(!digitalRead(redbtn)){
digitalWrite(redled,HIGH);
delay(150);}
else digitalWrite(redled,LOW);
if(!digitalRead(yellowbtn)){
digitalWrite(yellowled,HIGH);
delay(150);}
else digitalWrite(yellowled,LOW);
if(!digitalRead(bluebtn)){
digitalWrite(blueled,HIGH);
delay(150);}
else digitalWrite(blueled,LOW);
if(!digitalRead(whitebtn)){
digitalWrite(whiteled,HIGH);
delay(150);}
else digitalWrite(whiteled,LOW);
}
With this code we can control the LED with buttons. Now let’s consider lighting the lights in a random sequence. Take a look at the code below.
#define redled 9
#define yellowled 10
#define blueled 11
#define whiteled 12
int leds[] = {redled,yellowled, blueled, whiteled};
void setup(){
Serial.begin(9600);
pinMode(redled,OUTPUT);
pinMode(yellowled,OUTPUT);
pinMode(blueled,OUTPUT);
pinMode(whiteled,OUTPUT);
randomSeed(analogRead(0));
flashLed();
}
void loop(){
}
void flashLed(){
for (int i = 0; i < 4; i++) {
int shoosen_led = random(4);
flash(leds[shoosen_led]);
}
}
void flash(int led){
delay(200);
digitalWrite(led,HIGH);
delay(500);
digitalWrite(led,LOW);
}When we run this code, four times random lights light up between the LEDs
Now let’s connect the active buzzer and screen to our circuit
Add as in the diagram shown below
Try running this code, the full code is provided below
