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/

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)

Arduino – Programming

The programming in arduino in done through Embedded C. For beginners Embedded C is just like standard C except that it add a few functions to make it controller/board specific. Below are some functions  of Embedded C for arduino.I suggest you guys to learn standard c before working on embedded c.

• Structures
• setup() –This function is used to initialize initialize variables, pin modes, start using libraries, etc. The setup function will only run once, after each powerup or reset of the Arduino board.
