EIGHT LED WITH 74HC595 AND ARDUINO

Image
ARDUINO JANUARY 4, 2017
In this lesson, you will learn how to use eight large red LEDs with an Arduino without needing to give up 8 output pins!

Arduino  Code

int latchPin = 5;
int clockPin = 6;
int dataPin = 4; byte leds = 0; void setup()
{
pinMode(latchPin, OUTPUT);
pinMode(dataPin, OUTPUT);
pinMode(clockPin, OUTPUT);
} void loop()
{
leds = 0;
updateShiftRegister();
delay(100);
for (int i = 0; i < 8; i++)
{
bitSet(leds, i);
updateShiftRegister();
delay(100);
}
leds = 0;
updateShiftRegister();
delay(100); for (int i = 7; i >= 0; i–)
{
bitSet(leds, i);
updateShiftRegister();
delay(100);
}
} void updateShiftRegister()
{
digitalWrite(latchPin, LOW);
shiftOut(dataPin, clockPin, LSBFIRST, leds);
digitalWrite(latchPin, HIGH);
}


EIGHT LED WITH 74HC595 AND ARDUINO WITH BLUETOOTH

After creating the EIGHT LED WITH 74HC595 AND ARDUINO we decided to go to the next level by controlling it by the android app via cell phone. We added a Bluetooth and changed the Arduino code to receive message via Bluetooth and regarding the message controlling the  Arduino application in the loop function Download Eight_LED_with_74HC595 Download Android Code

CREATE PIANO AND MIMIC “MAKEY MAKEY” USING ARDUINO

ARDUINO JANUARY 7, 2017


This is our new Arduino project it’s a small piano that we have created using  passive buzzer we also tried to mimic the MAKEY MAKEY and  instead of the buttons we used fruits After creating the MAKEY MAKEY So how does it work? well its pretty simple all you have to do is touch the fruit and if it doesn’t work then that means you’re not touching the ground Here is the code

TILT ALARM (ARDUINO PROJECT)

In this project, we made an alarm using: switch ballpassive buzzerLEDBluetoothjumper wiresFM wiresBreadboard wiring board The idea of this project is when you tilt an object that has the switch ball taped to it the passive buzzer will make sounds and the LED will light up and if your phone screen will also be filled the color red if your object gets tilted The android app  Download Arduino Code Download Android Code

KEYPAD ARDUINO PROJECT

Image
In this project, we made a keypad passcode that when you type the password in the keypad a green led will light up. If you write the wrong password in the keypad the red led will light up. Now we will show you how to put together the project. From 2 to 9 this is supposed to be for the keypad and 12 and 13 are for the red and green LEDS then you connect the ground. and don’t forget to connect the ground to both parts of the breadboard. Diagram We built this using 2 LEDs, a keypad a breadboard and last is the Arduino. We wanted to add more into this project though so we decided to make an app that can be used to unlock and lock using an android app you can download it from here
so now as you can see in this picture this is our android app that we created. Download the android app Download Arduino Code from here

HUMAN BLOOD

Human blood is easily one of the most important parts of the human body ,its job is to transport oxygen,  nutrients, waste, and hormones around the body which is extremely important because if you didn’t have blood to transport all of these things to your organs your organs shouldn’t have the energy to function properly which would potentially kill you. Your blood helps your body in regulating your body temperature and PH levels. Your blood mainly consists of 3 layers the first layer is called the erythrocytes which consist of red blood cells their job is to carry oxygen & co2 around your body and they make up approximately 45%of your total blood volume the second layer of your blood is called the Buffy coat it is less than 1%of your blood volume it includes leukocytes  which are white blood cells which are the warriors of you your blood, your white blood cells fight diseases  the Buffy coat also contains platelets which help in blood coating so if you have a cut that’s the subst…
