relay and neutral terminal of mains. It gets connected to live terminal of AC mains via normally opened (N/O) contact when the relay energizes. If you want to operate a DC 12 volt relay then use a regulated DC 12 volt power supply for DC 12 volt Relay and remember that the circuit voltage not be exceeded more than DC 5 volts.

PIC based digital voltmeter author: Rajendra Bhatt - rajbex[pic]yahoo.com Introduction This project describes how to make a digital voltmeter using a PIC microcontroller. A HD44780 based character LCD is used to display the measured voltage. The PIC microconotroller used in this project is PIC16F688 that has 12 I/O pins out of which 8 can serve as analog input channels for the in-built 10-bit ADC. The voltage to be measured is fed to one of the 8 analog channels. The reference voltage for

Discuss the ethics of Milgram’s obedience study. In the years 1961-1962‚ Stanley Milgram - Yale University psychologist‚ conducted the first of the obedience experiments‚ which were also called "shock" studies. The research was invented to check if the people would be ready to harm somebody just to meet the requirements of the experiment. This essay will be focused on the ethical side of the study. Firstly‚ it will be presented how the experiment was performed‚ by describing all of the necessary
