BeagleBone – Motor interfacing

A DC motor is a type of motor which as the name suggests run on direct current. The DC motor which we use properly runs between 9V to 15V(may vary according to size).For connecting your Raspberry Pi with your motor you need an IC called L293D.Its is a dual H-bridge motor driver integrated circuit (IC). Motor drivers act as current amplifiers since they take a low-current control signal and provide a higher-current signal. This higher current signal is used to drive the motors.For the steps visit

BeagleBone – LCD interfacing

LCD stands for Liquid Crystal Display .The LCD can display messages in two lines with 16 characters each. It can display all the letters of alphabet, Greek letters, punctuation marks, mathematical symbols etc. It is also possible to display symbols made up by the user. Other useful features include automatic message shift (left and right), cursor appearance, LED backlight etc. It has got 16 pins in total and can be used in two modes 4 bit and 8 bit. Since the GPIO pins in Raspberry Pi is limited to 6 ,we will interface LCD in 4 bit mode.For info on how to interface visit

Arduino – ADC interfacing

An analog to digital converter is an electronic circuit which converts continuous signals to discrete digital numbers. In case of Arduino Uno we have a 10 bit ADC and the no of channels is 6 (A0-A5) .10 bit ADC means that when we convert analog value to digital ,we obtain the values in the range of  210 =1024 so the readings will be from 0 to 1023.The function that is used to read the analog values isanalogRead and the syntax is analogRead(A0) where A0 is the analog 0th pin.For more detail about ADC visit http://learningembedded.com/arduino/arduino-adc-interfacing/

BeagleBone – LED interfacing

A light-emitting diode (LED) is a two-lead semiconductor light source. It is a pn-junction diode, which emits light when activated.For connecting an LED we use the GPIO pins.For more information on LEDs  visit http://learningembedded.com/beaglebone/beaglebone-led-interfacing/

The DC motor which we use properly runs between 9V to 15V(may vary according to size).. For connecting your Arduino with your motor you need an IC called L293D.Its is a dual H-bridge motor driver integrated circuit (IC). Motor drivers act as current amplifiers since they take a low-current control signal and provide a higher-current signal. This higher current signal is used to drive the motors. The program below show how to control motor when a switch is pressed, In when input-1 is pressed , the motors move forward and when input-2 is pressed, the motor moves backward.

BeagleBone – Programming

Programming in Beaglebone can be done in many languages but the most commonly used is python script and Java Script.Python is an easy to learn, powerful programming language. It has efficient high-level data structures and a simple but effective approach to object-oriented programming. Python’s elegant syntax and dynamic typing, together with its interpreted nature, make it an ideal language for scripting and rapid application development in many areas on most platforms. visit http://learningembedded.com/beaglebone/beaglebone-programming/ for more details

Arduino – LCD interfacing

LCD is a type of display device that can display all the letters of alphabet, Greek letters, punctuation marks, mathematical symbols etc. HD44780 microcontroller (Hitachi) and can display messages in two lines with 16 characters each. It is also possible to display symbols made up by the user. Other useful features include automatic message shift (left and right), cursor appearance, LED backlight etc.The LCD can be connected in two ways ,one is 4 bit mode and other is 8 bit mode .Arduino has defined a special library for LCD which can be viewed on

BeagleBone – Linux Commands

Since Beaglebobe work on a linux distribution  so when working in the command line,it is very important to know the different commands.For using the different commands you much open the terminal and type in the commands listed below.The default username is root and the default password is blank.The command are list below can be studied in detail by using

$ man  <command>

Arduino – Seven Segment

A seven-segment display (SSD), is a form of electronic display device for displaying decimal numerals. It is of two types, one is common cathode(cc) and other is common anode(ca).In common cathode the ground is common  and in common anode the Vcc  is common . It is basically a collection of LEDs (7+1)  where 7 leds are correspond to abcdefg and 1 led is DP(decimal point)

BeagleBone – Installation

This section deal with the installation in your Beaglebone or Beaglebone black.The original Beaglebrone has no HDMI so we will connect it using SSH or USB (explained later on) h while in case of the black version which has an HDMI ,we can directly connect it with the display using the following things mentioned below.

• Micro USB lead
• USB power adapter
• Ethernet cable
• HDMI lead(only for Beaglebone Black)
• HDMI display(only for Beaglebone Black)
• microSD card (minimum 4 gb recommended)
• SD card reader
• USB keyboard and mouse

The OS used in Beaglebone is a linux distribution.For nore information visit

Raspberry Pi – PC Connection

If you don’t have a TV with HDMI port ,Dont worry !!

You can also access your Raspberry pi on your PC through PuTTY. PuTTY is an SSH and telnet client, developed originally  for the Windows platform. Secure Shell (SSH) is a cryptographic network protocol for secure data communication, remote command-line login, remote command execution, and other secure network services between two networked computers.
