Latest Electronics Projects Ideas for Engineering Students
1. RFID Based Door Access Control
The conception of entrance control is brought about by mean of a card, a parallel card reader and a control board is amalgamated with the server. This is a proximity card with a unique ID number incorporated in it. The card reader interprets the data and sends it to the control board, which is a microcontroller. This microcontroller tests the legality of the data with the incorporated server, which abides the database. The attached server is uploaded with the details of the worker for that unique ID number.
The control board confirms whether the person is permitted to enter the precise door or not. If the worker is genuine, then the person is permitted to enter the door.
The workers can be allowed in a particular doorway as per the designation. The entry control is used at this end. RFID technology employs frequencies inside the range of 50 kHz to 2.5 GHz. An RFID mechanism usually comprises the following constituents:
An RFID device that encloses data
An antenna employed to broadcast the RF signals amid the reader and the RFID machine
An RF transceiver that produces the RF indications
A reader that collects RF broadcasts from an RFID machine and passes the data to the host system for further action.
2. Automatic Solar Tracker
Automatic solar tracker begins to follow the SUN exactly from sunrise, all through the day, till sunset, and begins the work all over again from sunrise next day. On hazy weather day, it lingers motionless and grasps the SUN yet again as it peeps out of clouds. It does all this mechanically, by employing inexpensive and economical constituents, and is extremely accurate. Let us make out how all this is done.
There are 3 Electronic sections to be elucidated. First is the parallel sensor section. It makes use of the 555 timer IC in the mono-stable approach. Pin 2 or trigger pin of 555 is hooked up with a power separator network. Pin 4 which can be reset is hooked up with an extra power separating network.

Traditionally, wireless controlled robots make use of RF (radio frequency) circuits, which have its own disadvantages of restricted operational range, limited frequency range and limited control. This project introduces the use of mobile phone for robotic control. This technology is more controller friendly as it doesn’t interfere with other controllers and can use up to twelve controls. It also has the advantages of robust control and provides working range as large as the coverage area of the service provider. Although the look and capabilities of these robots vary, but they share mechanically movable structures under some form of control. The robots are controlled in three phases namely reception, processing and action. Here preceptors are sensors mounted on the robot and the processing is done by on-board microcontroller or processor. This robot works either with the help of motors or with some other actuators.
The robot is controlled by making a call on the mobile phone attached with the robot. In the course of the call if any button is pressed a ‘dual-tone multiple-frequency’ (DTMF) tone is heard at the other end of the call. The cell phone mounted on the robot perceives this tone and then the robot processes it by the ATmega16 micro-controller with the help of DTMF decoder MT8870.
