Controlling SmartDrive40 Using 3.3V Microcontroller (Serial Simplified Mode)

In this tutorial, I will explain some sample code to drive the two DC motors in sign-magnitude PWM mode, locked-antiphase PWM mode and simplified serial mode. Thus, all of the sample code that given in this tutorial will only drive two DC motors in clockwise by pressing SW1 and in counter-clockwise by pressing SW2.

Nowadays, most hobbyist like to use RC servo motor to control their robot or others than that which need a precise position while a cheapest price. For this project, we are going to discover how to control 2 RC servo motor together using Arduino Duemilanove with Arduino Input Shield.

Ultrasonic range finder MAXSONAR-EZ1 which can measure the range from 6-inch to 254-inch with also an incredibly small package with ultra low power consumption. It’s provided sonar range information with 1-inch each step. The interface format is include pulse-width, analog and digital output. For this project, we are going to interface this sensor with Arduino and display the output range in inch in LCD display.

To deal with computer keyboard, we have to know what kind of signal did keyboard giving when you press a key. For this project, we are going to interface the Arduino Duemilanove to computer through USB.
