Getting Started with Python

What is Python? Python is an open source general purpose programming language. It is designed in such a way to improve software quality, developer productivity, program portability and component integration. Python gives more importance to its code readability and its syntax allows programmers to program their idea in fewer lines of code than other programming languages like C does. It is used all round the globe for web designing, system programming, user interfaces, product customization, numeric programming etc. Why Python? Python language  is...

ADC_Symbol

Using ADC Module of PIC Microcontroller – Hi Tech C

Analog to Digital Converter (ADC) is a device that converts an analog quantity (continuous voltage) to discrete digital values. This is very useful when we want to do some processing on physical quantities, which are normally analog in nature. Most of the PIC Microcontrollers have built in ADC Module. Here we are using PIC 16F877A for demonstrating the working. ADC_Symbol ADC of PIC Microcontrollers have 5 inputs for 28 pin devices and 8 inputs for 40/44 pin devices. It is a 10-bit...

Push Button Switch

Using Push Button Switch with PIC Microcontroller

I hope that you have already read the first tutorial of Hi Tech C, LED Blinking using PIC Microcontroller. In that tutorial we blink LEDs connected to PORTB by writing to entire PORT and TRIS registers. In some cases we may want to set or reset individual bits of these registers. For that we can use the bit addressable feature of these registers. We have already seen in the previous tutorial that TRIS register is used to set the direction...

Blinking LED using PIC Microcontroller with Hi-Tech C

A lot of you may heard about microcontrollers and its applications. Well it is a bit difficult to start learning microcontrollers. And the guides and tutorials also do not start from zero level which makes learning far more difficult than anticipated. I have tried to start from zero level in here also. All you need is the simplest knowledge of electronics or digital circuits. But you surely should have a decent knowledge of C language. The software for programming Microchip microcontrollers...

Servo Motor

Interfacing Servo Motor with Atmega32 Microcontroller

Servo Motor Servo Motor is a DC Motor equipped with error sensing negative feedback to control the exact angular position of the shaft. Unlike DC Motors it will not rotate continuously. It is used to make angular rotations such as 0-90°, 0-180° etc. Stepper Motors can also be used for making precise angular rotations. But Servo Motors are preferred in angular motion applications like robotic arm, since controlling of servo motors are simple, needs no extra drivers like stepper motor and...

dc motor

Interfacing DC Motor with Atmega32 Microcontroller

In some of your electronic projects you may want to control a DC Motor with Atmega32 Microcontroller. We can't connect a DC Motor directly to a microcontroller due to following reasons. A microcontroller can't supply the current required for the working of DC Motor. ATmega32 Microcontroller can source or sink currents up to 40mA but a DC Motor needs current very much more than that. The negative voltages created due to the back emf of the motor may affect the proper functioning of the microcontroller. You may need to...

Servo Motor

Interfacing Servo Motor with 8051 using Keil C

A servo motor uses servo mechanism, which is a closed loop mechanism that uses position feedback to control the precise angular position of the shaft. Stepper Motors, which is an open loop system can also be used for precise angular control. But Servo Motors are preferred in angular motion applications such as robotic arm. Moreover controlling of servo motors are very simple, easy and needs no extra hardware like stepper motor. Usually hobby circuit servo motors have three wires. Two of them...

16x2 Character LCD

Interfacing LCD with Atmega32 Microcontroller using Atmel Studio

As we all know LCD (Liquid Crystal Display) is an electronic display which is commonly used nowadays in applications such as calculators, laptops, tablets, mobile phones etc. 16x2 character LCD module is a very basic module which is commonly used by electronic hobbyists and is used in many electronic devices and project. It can display 2 lines of 16 character and each character is displayed using 5x7 or 5x10 pixel matrix. 16x2 Character LCD Interfacing 16x2 LCD with Atmega32 Atmel AVR Microcontroller using Atmel...
