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

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

CREATE PIANO AND MIMIC “MAKEY MAKEY” USING ARDUINO

Image
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
