KEYPAD ARDUINO PROJECT



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.

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.

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

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); } 74HC595 ARDUINO
