PIC12F675 Tutorial 5 : A Temperature data logger using PIC EEPROM

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 regular intervals until full and after this it turns on the LED. The LED is really just for showing that something is happening and in a real data lo ...

PIC12F675 Tutorial 4 : Making an LM35 temperature recorder

This page shows you how you can make an LM35 an temperature recorder by using the 12F675 PIC microcontroller as the controller and data store. It generates serial output so that you can view the results on a PC and it also calculates the temperature reading in Fahrenheit sending both to the serial port at half second intervals. The project uses the code from the previous tutorials to report the temperature ...

How to interface GPS with PIC18F4550 Microcontroller

Global Positioning System is based on satellite navigation technology. A GPS Receiver provides the accurate location of an object in terms of latitude and longitude. Accurate time calculation with respect to GMT can also be done by using GPS. For more information on different data obtained through GPS, refer GPS Receivers. Here a PIC microcontroller has been interfaced with a GPS module to extract its posit ...

How to work with inbuilt ADC Module of PIC18F4550

A microcontroller, a digital device, can read, execute and transmit only digital signals. On the contrary, the outputs of the most of the transducers are analog in nature. Thus it is hard to interface these transducers directly with controllers. Analog-to-digital convertor (ADC) ICs are one way to make the analog input compatible with the microcontroller. Using an external ADC adds complexity to the circuit ...

Hee Haw Sound

This experiment creates a Hee Haw sound for an alarm. The diagram shows the number of cycles for the HEE and the time taken for each cycle, equates to a certain length of time. The frequency of the HAW is lower and the number of cycles must be worked out so that the time for the HAW is equal to the time for the HEE. This is simple when writing the program. The values loaded into the two files for the HEE ar ...

Your first PICMicro Project using PIC16F84

After doing two weeks on LCDs, I thought I'd spend a few weeks focusing on the number one question that I get asked; "How do I start working with the Microchip PICMicro?" The question is asked from a variety of perspectives and goals, ranging from somebody that just wants to become casually familiar with the chip to people who want to learn about the PICMicro to students that have been given an assignment t ...
