Here is my new electronics circuit for you. This is a brief description/ abstract for the project. Combinatorial digital circuit logic determining device is a circuit which determines the logic of any given combinatorial digital circuit. This is a very helpful tool to know the functionality of an unknown digital circuit. The device has probes which are plugged to the inputs and outputs of the digital circuit under test. This device then determines and displays the functionality of the circuit under test in the form of a boolean equation.

The circuit has number of probes equal to the number of inputs and outputs of the circuit under test. I have implemented it for two inputs and one output. Although, you can make slight modification of the code to make it work for as many inputs and outputs you want.

Automatic Water Level Controller With Error Indicator Alarm is an electronics project which I have done recently. Here is the brief description / abstract of it. The Water Level Controller with Error Indicator employs a simple mechanism to detect and maintain the water level in a tank or any other container by switches on/off the motor automatically when needed. The level sensing is done by a set of nine probes which are placed at nine different levels on the tank walls (with probe9 to probe1 placed in increasing order of height, common probe (i.e. a supply carrying probe) is placed at the base of the tank). Basically, level9 represents the “tank full” condition while level 1 represents the “tank empty” condition.
