Arduino Clock without RTC

Arduino Clock without RTC

This is simple project arduino as RTC, by this project you can learn how to handle key inputs, lcd interface, lcd contrast, eeprom and changing pwm frequency.

pin 2 – lcd rs
pin 3 – lcd – enable
pin 4 – lcd – d4
pin 5 – lcd – d5
pin 6 – lcd – d6
pin 7 – lcd – d7
pin 9 – lcd – contrast

pin 10 – key 1
pin 11 – key 2

connect wiring as per about and dump code!!!

Visitor Counter in IoT

Visitor Counter in IoT

This project count number of visitor in the time given, and shows in web. This work has embedded web server, so we can browse from any browser even from mobile. for this we need
1. Arduino Uno
2. ENC28j60 module
3. IR/Ultra Sound Sensor

connect ENC28J60 via ICSP/ISP interface, and connect ultra sound, based on pin map alter below two line and dump the code!!!

Simple Clock

Simple Clock

This project demonstrate RTC interface via I2C protocol and shows current temperature of environment. To do this, we need
1. Sakthi Kits
2. RTC Module
3. LM35
4. 9Volt Battery

Connect RTC via, I2C header
Connect LM35 output to A0

upload these code!! simple!!!

Density Based Traffic Signal

Density Based Traffic Signal

This small project will count the number of vehicle enters in four road, based on the frequency of arrivals, signal will switch, for this project you need

  • Arduino
  • 4 IR Diode
  • 4 IR LED
  • 4 Green LED
  • 4 Red LED
  • 4 Yellow LED
  • 16 330 Ohm resisotors
  • 4 10K resistors

connect all IR Diode serious with 10K and take output from that point and connect to arduino pin A0, A1, A2 and A3 for Road 1, Road 2.. Road 4 respectively.
connect all LEDs with 300 ohm in serious, plug 4 IR Led in 5V and Ground
connect all Green, Yellow and Red LEDs cathode to ground
connect Green, Yellow and Red by four group with arduino pin (13,12,11), (10,9,8), (7,6,5) and (4,3,2) for Road 1.. Road 4 respectively

burn blow code, and keep IR Diode and IR Sensor to face same direction, now when vehicle cross it count one. breath below code your can understand easily.

GSM based Fire Alarm

GSM based Fire Alarm

GSM based Fire Alarm system work with few external component, you need

  • Arduino
  • GSM Modem
  • H21A1 – IR Sensor
  • 10K and 330 Ohm
  • Bread Board and Connecting Wire

GSM connect with SoftSerial, for that connect Tx and Rx with 3 and 4 pin of arduino receptively,
connect sensor emittor with 330ohm to 5v and Ground
connect sensor detector with 10K to 5v and Ground
connect sensor detector to arduino anlog pin 0

burn code and you get alert,
before buring update your mobile number

Bluetooth Remote Control Toy

Bluetooth Remote Control Toy

I will show you how to transform an RC toy car to Bluetooth controlled through your Android smartphone!
to design this project we need

  • Arduino Uno board
  • L293D motor driver
  • HC-06 Bluetooth module
  • 4x LEDs for lights
  • 1x Speaker/Buzzer for horn sound

Install Bluetooth RC Controller application from Google App Store, Open Settings in this application, we can see the command mapping over here. This command are sent via BlueTooth serial socket.

In car side, connect HC05/HC06 with Arduino Serial port,
connect motor at 10, 11 and 6, 5
connect back leds at pin 3
connect front leds at pin 2
connect buzzer at pin 4 of arduino

burn this below code.

Simple Arduino Entry Counter

Simple Arduino Entry Counter

For beginners who interested to learn about arduino this project is very easy to lean and wire, we give you very short notes to know details about this project. Its have very few components,

1. 8 numbers of 330 ohms resistors
2. one 10K resistor
3. Bread board
4. Common Cathode Seven Segment
5. IR Diode
6. IR LED
7. Few jumper wires

Wiring
1. Connect 7Seg Common to GND pin of arduino
2. Connect A to G via 330 ohm in arduino pin 6 to 12.
3. Connect 10K to Analog Pin 0 with 5V in arduino.
4. Connect IR Diode cathode to ground and anode to Analog Pin 0
5. Connect IR Led to 5v with 330ohms in serious.

Dump this code, Keep IR diode and IR Led in same line to face each other, when interrupt accrue its counts one.
