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

BeagleBone – Buzzer interfacing

A buzzer or beeper is an audio signalling device, which may be mechanical, electromechanical, or piezoelectric. Typical uses of buzzers and beepers include alarm devices, timers and confirmation of user input such as a mouse click or keystroke.for information on buzzer

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.
