The different between these two IC`s. A Microcontroller is a specialized form of Microprocessor that is created to be self-sufficient and cost-effective, where a Microprocessor is typically designed to be general purpose use like in a Personal Computer (PC). The Microcontroller is the integration of a number of useful functions into a single IC package.

These functions are: A Microcontroller generally has the main CPU core, ROM/EPROM/EEPROM/FLASH, RAM and some accessory functions (like timers and I/O controllers) all integrated into one chip. Microprocessor IC is generally just the CPU core itself, although nowadays it might have some accessory parts also integrated to the same chip (for example cache memory). Microcontrollers IC`s are frequently found in consumer electronics like Monitors, Televisions, in automobiles, washing machine, office machines, toys, appliances and etc. I still could recall during the early 90`s and before, many of the Analog Monitors that I repaired does not have the microcontroller circuit. The functions of the Monitors were all controlled by variable resistors. Let say if the Monitor brightness have problem we just have to follow the brightness control starting from the variable resistor in the front panel and trace it backward and it was very easy to locate the fault. You can use this method to trace on other circuit as well like the Pincushion circuit, Horizontal size circuit, Vertical Size circuit and etc. However when the newer type of Monitors (Digital Monitors) that use the Microcontroller circuit came into the market I have problem in finding those fault and you can`t follow the way that you used in finding fault in an Analog Monitors. Below I cover some of the most frequently asked questions from fellow members: Question 1: Assuming a...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
