# Simple 5V DC Power Supply

In any electronic products or projects there is always a source of power for the system to work. This is called a power supply. The source of this power can come from different sources like the mains AC voltage, a battery or even from a renewable power source like a solar panel wind turbine or fuel cell to name just a few. The most common source of power is usually the mains AC, with this power, we need a transformer to convert the 220V 50Hz mains or the 120V 60Hz if you are living in the United States of America to a lower voltage required by the electronic circuit, this can be typically between 6V and 12V when 5V regulated DC is needed. In this article we are going to design a simple 5V DC power supply that can be used to power your Microcontroler projects using the 7805 voltage regulator.

# Digital Thermometer using PIC Microcontroller and LM35 Temperature Sensor – MikroC

Temperature sensors are very important in many projects especially in temperature logging devices and alarms. In this article we are going to design a digital thermometer using MikroC Pro for PIC compiler. This digital thermometer is built around the LM35 which is a precision integrated-circuit temperature sensor whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. Its output changes by 10 mV per °C so there is no need for calibration. It can measure a wide range of temperature from −55 to +150°C

# Digital Thermometer using PIC Microcontroller and LM35 Temperature Sensor – XC8

Temperature sensors are very important in many projects especially in temperature logging devices and alarms. In this article we are going to design a digital thermometer using MPLAB XC8 compiler. This digital thermometer is built around the LM35 which is a precision integrated-circuit temperature sensor whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. Its output changes by 10 mV per °C so there is no need for calibration. It can measure a wide range of temperature from −55 to +150°C

# P1 Semester Report Sample 1

To fulfill the requirements of the national diploma in Electrical Engineering or Computer Systems, the student must successfully complete all academic requirements as well as the work integrated learning (P1 for 6 month and P2 for 6 month) component. This sample 1 is for a student doing a P1 in Electronic Security Industry, but it can be used for other industries as well, this is just a template.

# Digital Clock using PIC Microcontroller and the DS1307 Real Time Clock – XC8 Compiler

Real Time Clock and Calendar functions are very important in many projects especially in data logging devices where a real time stamp is required in each record. This clock uses the DS1307 which is a low power serial real time clock/calender with full binary coded decimal (BCD) clock/calendar plus 56 bytes of Non Volatile Static RAM. This chip provides year, month, date, hour, minute and second information. The end date of months is automatically adjusted for months fewer than 31 days including leap year compensation up to year 2100.
