EasyEDA – A Cloud based PCB Design Software

Cloud computing is an internet based computing which relies on sharing computer resources. It enables us to use computer resources or processing power as a utility similar to using electricity. So we don't need to make big computer infrastructure in our building, just use the cloud resources whenever there is a need. Nowadays everything become cloud computing, like cloud storage, word processing, business analytics etc. What is the role of cloud computing in electronics ? The question ends here, EasyEDA. It...

I²C Communication with PIC Microcontroller – MPLAB XC8

I2C or IIC or I2C stands for Inter-Integrated Circuit. It is a very popular multi-master, multi-slave serial communication interface developed by Philips. I2C uses two bidirectional open drain data lines, Serial Data (SDA) and Serial Clock (SCL) with pull up resistors as shown below. Unlike UART, you can connect and communicate to multiple devices using the same I2C bus. I2C Communication I2C is a master slave protocol. It means that devices connected to I2C bus will be either master or slave. The master is the...

Using ADC of PIC Microcontroller – MPLAB XC8

In this tutorial we will learn, how to use the ADC module of a PIC Microcontroller using MPLAB XC8 compiler. For demonstration we will use the commonly available PIC 16F877A microcontroller. Every physical quantity found in nature like temperature, humidity, pressure, force is analog. We need to convert these analog quantities to digital to process it using a digital computer or a microcontroller. This is done by using Analog to Digital Converters. An Analog to Digital Converter or ADC is a device...

Generating PWM with PIC Microcontroller – MPLAB XC8

Pulse Width Modulation (PWM) is the one of the simple and most commonly used technique to produce analog voltages from digital signals. It has a wide variety of applications such as Digital to Analog Converter (DAC), DC Motor Speed Control, Sine Wave Inverters, Brightness control etc. PWM signals are ON - OFF signals (HIGH or LOW) (hence the name Pulse) whose HIGH or ON duration is changed (hence Width Modulation) in accordance with our requirements. The fraction of time period for...

Access Raspberry Pi directly from Windows PC

Usually beginners require a display, keyboard and mouse for using Raspberry Pi. But being a linux based system, the Pi can be accessed through a variety of methods like SSH (check our Raspberry Pi SSH tutorial), VNC (check our Raspberry Pi VNC tutorial) etc.. But these methods require an already existing network consisting of a router or other network devices. It would be easier to directly connect the Pi to the computer and work with it without any additional hardwares like router. But...
