Introduction There are varieties of digital temperature logger projects available online based on different microcontrollers. The one I am going to talk about is based on a Microchip’s 8-pin microcontroller, PIC12F683. It reads temperature values from a DS1820 digital sensor and stores in its internal EEPROM. PIC12F683 has 256 bytes of internal EEPROM and we …

This post provides the PWM code (using C language) and Proteus simulation for PIC18F452 micro-controller CCP1 and CCP2 modules ( written using MPLAB and HI-TECH C18 compiler ). There are many uses for PWM signals, e-g you can control dc motor speed using PWM. CCP is the name for the built in PWM module in …
Programming microcontrollers isn’t hard. Building a programmer makes a great first electronics project. The goal of this instructable is to explain the simple ‘in circuit serial programming’ method used with Microchip PICs. Step 1: Why ICSP? Programming a big DIP (through hole) chip is easy. Pop it into a socketed programmer, burn, and return to …
After writing quite a bit of experimental tutorials on PIC16F series of microcontrollers, I thought of moving forward to the enhanced-range family of PIC microcontrollers, the PIC18F, which was introduced by Microchip in late 90s. Although PIC16F series are excellent general purpose microcontrollers, certain limitations have emerged, such as, they have limited program and data …
This project is used to control the brightness of the lamp or can be used to control the speed of the fan. The system consists of 3 block they are Zero crossing detector Microcontroller (Atmega8) Load Driver (BT136)As the name implies the zero crossing detector generates pulses for every zero crossing of the input AC …
Introduction The Juicer is a wirelessly controlled, programmable juice maker which will mix each ingredient of a recipe to the exact proportions every time. The Juicer will take a recipe selection serially via either the keyboard or the wireless remote and dispense the juices into the cup below. Force and Photo sensors are incorporated to …
Some of the fruit and vegetables we eat can be used to make electricity. The electrolytes in many fruit and vegetables, together with electrodes made of various metals can be used to make primary cells. One of the most easily available vegetable, the ubiquitous lemon can be used to make a fruit cell together with copper and …

Developers can implement simple sensing functions with TI’s lowest-cost microcontroller family Texas Instruments (TI) on November 10, unveiled its lowest-cost ultra-low-power MSP430 microcontrollers (MCUs) for sensing applications. Developers can now implement simple sensing solutions through a variety of integrated mixed-signal features in this family of MSP430 value line sensing MCUs, available for as low as …
I recently had the need to carefully measure a voltage with a microcontroller which lacks an analog-to-digital converter (ADC), and I hacked together a quick and dirty method to do just this using a comparator, two transistors, and a few passives. The purpose of this project is to make a crystal oven controller at absolute minimal …
Step 4: Identify Memory Needs Flash and RAM are two very critical components of any microcontrollers. Making sure that you don’t run out of program space or variable space is undoubtedly of highest priority. It is far easier to select a part with too much of these features than not enough. Getting to the end …
