electronic projects without ic
Post: #1

I am Sangamesh..I want simple electronics projects without using IC...
Post: #2
The last time I did a DIY electronics project were the grinding units for portable radios, so that money could be saved for the batteries in the early '70s.

Circuit list of Mini Electronics Project:

1. Water level indicator: This water level indicator project uses a simple mechanism that helps detect and indicate the water level in an upper tank or in any other water container. It can be used in hotels, factories, apartment houses, commercial complexes, drainage, etc.
2. Password-based door lock system using the 8051 microcontroller: this system demonstrates a password-based door lock system where once the correct code or password is entered, the door is opened and the affected person has access to the secured area. After a while, the door would be closed. Read this publication completely for more information.
3. Robotic vehicle controlled by cell phone: this is a simple circuit of robotic vehicle controlled by cell phone based on DTMF without using microcontroller. It can be used in industries and surveillance systems.
4. Human detection robot that uses the 8051 microcontroller: the main principle of the circuit is to detect the human detection sensor used by the human being. The wireless robot is manually operated using a PC. The wireless technology used here is radio frequency technology. The data is transmitted to the receiver via RF.
5. Robot controlled by SMS: robot controlled by GSM or robot controlled by SMS is a wireless robot that performs the necessary actions by receiving a set of instructions in the form of a Short Message Service (SMS).
6. Electronic home appliances operated by remote password: this circuit explains how to control electrical appliances with an Android device. Here, the Bluetooth module is interconnected to the 8051 microcontroller. This Bluetooth receives commands from the Android application device via wireless communication.
7. Metal detector Robotic vehicle: Landmines buried underground cause threats to lives and affect the nation's economy. The detection and elimination of these mines manually is a dangerous task. So, we use a metal detection robot that works with RF technology.
8. Solar tracking solar panel: this article describes the circuit that turns the solar panel. This solar tracking solar panel consists of two LDR, solar panel, stepper motor and ATMEGA8 microcontroller.
9. DC motor speed control by pulse width modulation: this pulse width modulation technique is the most efficient way to manually manage the speed of our DC motor.
10. Water level alarm with 555 Timer: This is a simple and low cost hardware project that uses a 555 timer circuit. The objective of this project is to design a water level detection alarm with simple hardware and Low cost without compromising the performance of the device.
