What’s Holding You Back? The TOP 4 Excuses That Prevent Success

image-221
Death is not the greatest loss in life. The greatest loss is what dies within us while we live (Norman Cousins). On which side of these crazy excuses are you? Oh I am not educated, Oh I don't have enough money, Oh I don't have connections, Oh I am too late!!! As it stands now, an average individual has their life mapped like this: Go to school. Get good marks. Graduate and land a lousy job with a reputable company. Chase the last Friday of the Monday until the day you get the news that the company is laying you off. Get your provisional funds get out. Sounds easy and nice, doesn't it?

What Successful People Do Differently

image-218
When it comes to the laws that govern success, nothing else matters than this statement: Try and fail, but don't fail to try. These little eight words are at the heart of this blog. They mirror our ethos. You will never achieve anything amazing until the day you start trying and fail over and over and get over it to try again. And again. That guiding principle was the star that guided legendary entrepreneurs like Thomas Edison. Today we are basking under an electric bulb which Thomas kept trying to build but failed more than nine hundred times. That's 999 times, to be exact. How many South Africans do you know who can fail twenty times and keep going?

Microcontroller Interfacing – Basics

image-262
Microcontrollers have become very useful in embedded design as they can easily communicate with other devices, such as sensors, switches, LCD displays, keypads, motors and even other microcontrollers. A microcontroller is basically used as the brain or intelligent processing unit to control other devices connected (interfaced) to it in embedded systems just like a PLC in industrial automation. To interface a device to a microcontroller simply means to Connect a device to a microcontroller. This article will make it easier to anybody with very limited experience in electronics to learn how to interface commonly used devices like an LED, a switch, a transistor, a relay, a display, a keypad, a buzzer and so on to a PIC microcontroller.

A microcontroller is basically used as the brain or intelligent processing unit to control other devices connected (interfaced) to it in embedded systems just like a PLC is in industrial automation. Interfacing a device with a microcontroller in simplest terms simply means to connect a device to a microcontroller. This article will make it easier to anybody with very limited experience in electronics to learn how to interface different sensors widely with a PIC Microcontroller.

Interfacing DC Motor with PIC Microcontroller – MikroC

image-1636
DC motors are used in many industrial, commercial, and domestic applications. We have DC motors in toys, irrigation pumps, robotics, Drills and in many applications. In this article, we are going to learn how to interface a DC motor with a PIC Microcontroller, rotating it in either the clockwise or anticlockwise direction using mikroC Pro for PIC Compiler

Interfacing a Relay with PIC Microcontroller – XC8

image-254
A relay is an electromagnetic switch which is used to switch High Voltage/Current using Low power circuits. Relays isolate as well low power circuits from high power circuits, this is a good feature especially for safety reasons a section of the circuit with high dangerous voltage/current could be isolated from the user. When a low voltage is applied to the relay (coil wounded on a soft iron core), this coil becomes a magnet which in turns energizes the soft iron core which closes or open the high voltage/current contacts of the relay. A relay can be used to switch higher power devices such as motors, light bulbs solenoids etc. In this article we are going to learn how to interface a relay to a PIC Microcontroller, we will learn as well how to control devices connected to the relay using MPLAB XC8 compiler.

DC Motor Speed Control using PWM of PIC Microcontroller – mikroC

image-2702
DC motors are used in many industrial, commercial, and domestic applications. We have DC motors in toys, irrigation pumps, robotics, Drills and in many applications. In real life applications turning a motor ON in clockwise or anticlockwise directions or turning it OFF is not always all that is required. The speed of rotation has to be controlled as well. In this article, we are going to learn how to control the speed of a DC motor using the Pulse Width Modulation of a PIC Microcontroller using mikroC Pro for PIC.

Interfacing Matrix Keypad with PIC Microcontroller – XC8

image-249
Keypads are small keyboards that are used to enter numeric, alphanumeric or select configuration data to microcontroller systems. Keypads are available in a variety of sizes. The common sizes are 3x3, 4x3 and 4x4 keypads. A matrix keypad is basically a combination of push-buttons in a way to form rows and columns. In this way the number of input/output pins necessary for their connection to a microcontroller is reduced. A 4x3 keypad requires 7 input/output pins instead of 12 and a 4x4 will require 8 input/output pins instead of 16 pins. Keypad is a widely used input device with lots of application in our everyday life: Telephone, ATM, electronic lock, Calculator, Industrial process, Timers etc. In this article, we are going to learn how to interface a matrix keypad with an LCD display using Microchip XC8 compiler.
