Here is a Simple Temperature Display Circuit using LCD ( Liquid Crystal Display ). For Heat Sensor we have used IC LM35 (Precision Centigrade Temperature Sensors ) whose Output voltage is linearly proportional to the Celsius (Centigrade) temperature. Output of LM35 IC is 10mv/degree centigrade for eg if temperature is 35 degree then the output of sensor will be 350mv or 0.35V For working with LCD it is necessary to have Microprocessor. We have used Arduino Controller Board which is AN OPEN-SOURCE

In the story “The Circuit” the family must overcome many challenges and they must remain strong. There are many disadvantages associated with being migrant workers‚ for instance‚ they must survive on a very low income along with caring for and feeding their families. The family deals with the challenges very well and despite being poor‚ they are always kind and caring for one another. For example‚ the family’s housing is poor and inadequate. In the text it states that “The garage was worn down

As part of the course it was necessary to identify and submit a project using electronic hardware. The nature of this project was to develop‚ build‚ test and present an electronic project that was software controlled by a programmable integrated circuit (PIC). I designed and developed a working system that would automatically cover an outside seating area when rain was detected.

the main goal of this is something extraordinary in this field. The main point of this thesis was to bring out the creativity one can use by creating a Nokia 6600-controlled Remote Control (RC) Car. The Remote Control (RC) Car is a Firefox Transmitter 1:20 Radio Control (R/C) Buggy. The full functions of the RC car are to move forward‚ backward‚ reverse‚ left/right turn and to stop. Through the power of creativity‚ the proponent thought of something unique and having something out-of-the-ordinary

objective of this report is to illustrate the entire process of bringing an audio amplifier from a circuit diagram to a finished‚ working product. The basis of the amplifier will be the LM386 chip and as such‚ this will be looked at in further detail along with other technical features of the project. Aims and Objectives The overall objective of this project is to design and build the circuit for a stereo output audio amplifier whilst ensuring a high sound quality at all input frequencies and
