No doubt, electronic devices are saving a lot of manpower and un-necessary effort. In this article, we will be discussing the “Electronic eye” circuit that is popularly known as the magic eye.

This circuit can be used in devices to detect the presence of light automatically and operate the circuit accordingly. We have also described the features of the main components used in the circuit to make you understand the working of the electronic eye more clearly.

Electronic Eye

The electronic eye uses a photodetector to detect the occurrence of a beam. After that, based on the light intensity, this device activates the light like when it becomes dim. When this device works automatically then it removes physical switching of the device & therefore reduces the manpower. In this project, an LDR is used to detect the light when it drops on the circuit.

In automobiles, when horns are applied then noise pollution can be generated and creates many issues for humans. To overcome this problem, the mobile horn system is developed which reduces noise pollution. In every vehicle, RF transmitter & receiver is included. Once the vehicle driver presses the horn then the transmitter sends the RF signal.

This signal arrives at the automobile ahead of the primary vehicle. In this project, the RF receiver is connected to the next vehicle that gets the signal & the controlling unit works the buzzer within the vehicle. Thus the next vehicle driver can simply listen to the buzzer noise without troubling the public. For different vehicles, separate codes will be sent like LMV, TW, HMV. The program of the microcontroller can be written in assembly language.

Accident Alert System of Trains

Once the train travels through the railway track and if any train comes ahead of it, then the infrared rays will reflect from the receiver & transmits the signal toward the microcontroller. The distance of the obstacle from the train can be analyzed by the microcontroller, stops the train & generates a siren. This project is applicable for every train by connecting on the track so that train accidents can be avoided. This project is cost-effective and accurate, so applicable in modern trains.

In a transformer, the step-up is to amplify voltage rating of the main turn by determining the main coil length to the measured length value after that number of twists was 396, which was twisted up to 400 for simple calculation of the minor number of twists, so minor was estimating transformer ratio.
