Arduino Based Music Player

Engineeering Projects
arduino based music player

The project posted here is of simple music player system based on Arduino uno board and SD card module. As we all know that Arduino can deal with digital signals or square signals only if we wish to work with sine waves we have to use further processing circuits. Previously we had posted Tune Player using Arduino for demonstration of using PWM pin of Arduino. The audio signal is sine wave thus we have used PWM pin and OP-amp for audio output. In order to generate a pure audio signal…

receiver circuit of arduino and rf controlled robot

Arduino and RF Controlled Robot ‘ROBOT’, as you know were introduced much earlier in the fifties. People could not afford those massive devices because of the cost they were tagged with. But now, to make it available to common people as well, our team developed a robot that is based on a simple platform like Arduino. Due to the fact that it uses RF remote control, using this robot is much easier. The omnidirectional robot works smoothly within a range of up to 100 meters. Adding more to its benefit,…

Arduino Based Data Logger (Temperature)

Engineeering Projects
arduino based data logger

The project described here is a simple Arduino Based Data Logger which can be used at any place where data is needed to be stored for further processing and monitoring. The project posted here basically store temperature, humidity with date and time in regular intervals on an SD card or a computer, or both. The wide range of operations and data rate of 12 samples per minute make this circuit more versatile and attractive at the same time. The data logging can be adjusted as per desire by changing the…

Fingerprint Attendance System using Arduino

The project posted here is a simple Fingerprint Attendance System using Arduino and can be very useful for any place where attendance is taken for maintaining registers like offices, schools, etc. Previously, we had posted RFID based attendance system, Arduino Fingerprint Sensor Lock, etc. The project posted here utilizes a thumb impression for taking attendance. The Fingerprint Attendance System using Arduino is based on a simple algorithm called matching algorithm and is compared with previously stored templates of fingerprints against the user’s fingerprint for authentication. Maintaining a register for attendance is…

ultrasonic water level meter transmitter circuit

Wireless Ultrasonic Water Level Meter using ATmega328 Water level indicator is one of the most popular projects over the internet but the problem with that is, it uses metal electrodes as a result corrosion is occurring. When we pass DC in water it starts to react with the metal in presence of oxygen and corrosion is occurring. This problem is minimized by using alternating current instead of direct current but there is always the risk of electric shock which can be dangerous if is handled by a non-technical person. By…

Arduino Based Automatic Call Answering Machine

Engineeering Projects
author prototype of automatic call answer machine

The project “Arduino and GSM Based Automatic Answering Machine” is designed to answer the phone call with prerecorded message when we are unable to attain call. Sometime in this busy world we might not be able to attain the phone call due to several reasons (generally when we are in bathroom or watching movie in cinema or forget mobile in home). These calls might be important i.e. call might be from office or business call which cannot be ignored. Thus, the project posted here receive the call after three rings…

10 Level Battery Charge Indicator Circuit

Engineeering Projects
10 level battery charge indicator

We already indicates state of battery using battery status indicator circuit and battery voltage state indicator using 741 IC, this time we indicate battery status in 10 different levels. The project “10 Level Battery Charge Indicator Circuit” is designed using comparator IC LM3914, used to indicates charge of battery in 10 different level. The project uses 10 LEDs to indicate the charge of battery in 10 level i.e. each glowing LED indicates 10% of charge in battery. Let say, if seven LEDs glow, the charge available in battery is 70%. It…

CCTV Switcher Circuit using Timer IC 555

Engineeering Projects
cctv switcher circuit using 555 ic

Here is a simple project CCTV Switcher circuit using timer IC 555 and decade counter IC 4017. The basic function of this project is to switch between different CCTV cameras sequentially i.e. one CCTV output is displayed on TV at a time. A CCTV (Closed Circuit Telephone) camera is used for video surveillance by using a video camera. Sometimes one CCTV camera is not sufficient for surveillance entire area thus we have to use multiple cameras to cover the entire area of surveillance. The circuit posted here control four CCTV…
