In this small blog post, I am sharing some of the most popular and easy yet interesting enough electronics projects for science students or EE students. These projects are covered well with extensive details of circuit design concept and their working. If you are one looking for interesting ideas to make your next school project, you might like to consider the below projects:
1. Remote Controlled Light Switch
1. Remote Controlled Light Switch
This IR LED and TSOP based circuit trigger the relay when IR signals are received by TSOP IR receiver. Check out the complete remote controlled light bulb circuit.
2. Automatic Room Light Controller with Visitor Counter
2. Automatic Room Light Controller with Visitor Counter
This simple circuit tracks the visitors entering and exiting the room and turns off the room when there are no one in the room, else keeping the lights on. Find the project here: Automatic room light controller
3. Metal Detector Circuit
3. Metal Detector Circuit
This simple circuit works similar to traditional metal detectors, beeping while brining in the metal close to the circuit. Full project: metal detector circuit
4. Temperature Controlled Fan with Automatic Speed Control
4. Temperature Controlled Fan with Automatic Speed Control
This circuit uses a temperature sensor which sense the current temperature and adjust the speed of the fan accordingly. Find here the circuit details: temperature controlled fan circuit
5. LM386 Audio Amplifier Circuit
5. LM386 Audio Amplifier Circuit
This audio circuit uses IC LM386 to amplify the sound received through mic and provide output on a 8 Ohm speaker. See the full circuit: LM386 Audio Amplifier Circuit
6. PIR Sensor Based Intruder Detector
6. PIR Sensor Based Intruder Detector
This is the simplest project which just uses a PIR sensor module connected with a LED. When there is any human movement in the range of PIR sensor, the LED turn on. Instead of LED, we can also connect a buzzer to start the alarm when motion is detected.
See the circuit details here: PIR Sensor circuit
7. 100W Inverter Circuit
See the circuit details here: PIR Sensor circuit
7. 100W Inverter Circuit
This 100 watt inverter circuit design converts 12V DC to 220V AC to run home appliances. This circuit just demonstrates how to use DC source to converter into AC. See the full circuit design: 100 watt inverter circuit
8. IR Transmitter and Receiver Circuit
8. IR Transmitter and Receiver Circuit
This is a great demonstration of IR transmitter and receiver in a circuit. It has two parts, one acts as IR transmitter and other acts as IR receiver. Check the full circuit here: IR Transmitter and Receiver
