Cell Phone Detector: This is a simple circuit which helps to detect the presence of an activated cell phone by detecting the signals in the frequency range of 0.9 to 3GHz. Car Parking Guard Circuit Using Infrared Sensor: This circuit helps the person in the driving seat in such a way that it gives an alarm if there is any obstacle or a wall while parking or while driving in reverse. It is used in industries to control the liquid level automatically. Water Level Controller using 8051 Microcontroller: Here we are designing the circuit which is used to detect and control the water level automatically in overhead tank using 8051 microcontroller. Electronics Projects for Engineering Students: You may get best idea by reading all these project ideas and if you are interested, you may give few suggestions, comments, new electronics projects ideas also. We have collected best electronics projects list from various resources and listed them below in a tabular form. For those people, the below list of electronics projects ideas would be more helpful. They can get good knowledge on electronics only after doing some major projects or Mini Projects on Electronics in their engineering. We found that many people are showing interest to learn electronics concepts by joining in various electronics branches like ECE, EEE, etc. Related Post: Latest Electronics Projects for Engineering Students As day by day its importance growing at rapid rate. These concepts are very interesting to learn also. This electronics concept deals with various small and large circuits which may include concepts like diodes, batteries, resistors, integrated circuits, etc. So, it is very important and beneficial to us if we learn some basic things about electronics. In my case, what worked best: the longest one is shared between the pwm pin and the piezo, the shortest one goes to GND and the middle one goes to the other pin of the piezo.Electronics Projects – The projects which are having more demand in engineering level and especially very useful for ECE and EEE students. We are all well known that we cannot imagine our life without electricity even for single day as it became a part in our life. Hi, thanks! I noticed that the autotransformer has 3 different sizes pins. If anyone can find similar transformers on Mouser I'd be interested in seeing it. Also ozitronics posted some data (see picture) on his 'autotransformer' with similar resistance and 91mH/2.1mH inductance. Here is the transformer that I measured: Pin1-2 154ohm and Pin 2-3 8ohm Pins 1-3 is ~161ohm. The auto-transformer has three leads and you can measure the resistance across the leads to determine which is which. If anyone can explain the phyisics behind its operation, pleas chime in! thanks. The black blob is a pulsing square wave that the Arduino can produce. an Auto Transformer and a 'black blob' of circuitry. Go to the dollar store and purchase their Intruder Alert noise maker and your'll find. 
Arduino voltage booster (might be totally useful to another project though!).Arduino charge pump to boost the voltage (cool idea though).astable multivibrator as suggested by some piezo MFG.Many forum suggestions exist and I tried all these without success: there is zero good information on the internet.
It is super simple and as loud as your fire alarm. Hey all! I struggled with making a loud piezo buzzer from 5volts.
