Detecting colour of an object can be an interesting and useful electronic application. It can be realized using a colour sensor like TCS3200 and a general purpose microcontroller like AVR ATmega32. TCS3200 Colour Light to Frequency Converter Chip TCS3200 chip is designed to detect the colour of light incident on it. It has an array

Knowingly or unknowingly the RFID technology is used by us in our day to day life. The most familiar example is seen in MNCs, schools and offices for daily attendance or automatic door opening system. The RFID contains two parts, namely, tag and receiver modem. When an RFID tag comes in the range of receiver, the tag gets

A GSM/GPRS Module like SIM300 can be used for any embedded application that requires a long range communication, like a robot in Chennai controlled by a person sitting in New Delhi! Or simply a water pump in a rice field turned on in the morning by a farmer sitting in his house few kilometers away! You have

Since iRobot hasn’t provided linux users with a way to use the command module, I had to figure it out myself. Don’t be intimidated, its not hard at all, really. All you need to do is run a couple of scripts. Lets get started, shall we? Step 1 Get the goods For this tutorial, I’m assuming you have
In this tutorial we will discuss a simple PC controlled robot. The Robot PC link will be a RS232 serial line. The robot will have only five commands. Move forward (RS232 char ‘F’ or ‘f’) Move backward (RS232 char ‘B’ or ‘b’) Turn Left (RS232 char ‘L’ or ‘l’) Turn Right (RS232 char ‘R’ or

A microcontroller is a device which has an inbuilt processor surrounded by few dedicated hardware modules. Once the microcontroller initializes them they start operating on their own. In case of an ADC it will do the sampling and digital to analog conversion all by itself and keep the converted data in its buffer so that
