LCD:LCD's typically have 16 data pins and 2 for the LED backlight.

Character LCDs use a standard 14-pin interface and those with backlights have 16 pins.

There may also be a single backlight pin, with the other connection via Ground or VCC pin. The two backlight pins may precede the pin 1.

LCD:

GSM: SIM 900: It can accept commands from microcontroller UART

Works on power supplySpeaker and Microphone Jacks onboard for voice

Onboard PCB antenna Small size It Can do basic functions which can be done via normal phone like calling, send sms,

access data through GPRS etc. Plug and play device Serial port and debug port can help user easily develop user’s applications

ALCOHOL SENSER:

ALCOHOL GAS SENSOR:

This alcohol sensor is suitable for detecting alcohol concentration on your breath, just like your common breathalyzer.

It has a high sensitivity and fast response time. Sensor provides an analog output based on alcohol concentration.

The sensor needs 5V power supply to operate.

FEATURES:High sensitivity to alcohol and small sensitivity to Benzine

Fast response and High sensitivity

Stable and long lifeSimple drive circuit of 5V DC with analog output

Operation Temperature: -10 to 70 degrees C

APPLICATION:Breath AnalyzerBlood Alcohol Concentration Checker

Alcohol Gas Sensor

Advantages :drunk and driving and thus avoiding accidentsProtect the human Small space covered in vehicleEasy to installControl vehicle through GSM

BUZZER:

Buzzer is a audio signal device

Works on electromechanically or piezoelectric Circuit.

Buzzer act as alarm of the circuit

The vibration of metal plate causes a sound
