Multiple Servomotors

Multiple Servomotors

Using a modified version of the last program, we can control as many servomotors as we have I/O lines on port B. In the next listing, we will control two servos in the same manner as we controlled a single servo in the previous program. The circuit is shown in figure 4 (below). The program […]

12F675 Tutorial 5 A Temperature data logger using PIC EEPROM.

12F675 Tutorial 5 : A Temperature data logger using PIC EEPROM. using pic microcontroller

EEPROM is useful for storing long term data such as data logger information and this PIC microcontroller EEPROM project saves the temperature from an LM35DZ IC to the PIC’s internal long term data storage area.  The project follows on from the last project using the virtually the same hardware. It stores temperature readings internally at

Rotary Encoders schematich

Rotary Encoders

Rotary encoders are very versatile input devices for microcontroller projects. They are like potentiometers expect of digital nature and unlike analogue potentiometers they never wear down. Rotary encoders not only provide 360 degrees of rotational freedom they also allow digital positioning information to be gained without the use of analogue to digital converters (ADCs). When
