The purpose of the project is to build uncomplicated voice recognition system based on M32C/84 microcontroller. The main part consists of telephone, some amplifiers, and development board.The project used to operational amplifiers in the analog part, the first one, provide amplification to the signal of 220mV p-p generated by signal transducer (a microphone electret) and the preamplifier, in this case a telephone handset. The second stage translate signal 2.5V over to avoid the negative part and thus adapt it to the A/D converter input. The project used LMC6084 and LMC6484 ...

This M32C/84-based office message board project allows you to display a preprogrammed message like "do not disturb", "in the Lab", "At Lunch" etc on the LCD positioned at the door. The project has a keypad which is placed on a desk. On this keypad there are 15 buttons and 6 LEDs for control and indicator. This keypad is connected to the SKP via a cable. The SKP with its 3 buttons, 3 LEDs and LCD screen are placed at the entrance to the users cubical/office.In this project, user can select ...

The aim of the project is to build an interface between the user interface controller and resistance mechanism on a stair-step exercise machine. This M16C/62P microcontroller-based system gives you control over the resistance level instead of having to use one of the machine’s preset resistance levels.The project will determine what the original system was trying to do, and adapt it into a usable output. The DC motor and mechanical wiper are replaced with an Analog MUX and a Futaba RC Servo. The 8 fixed resistance levels are replaced with a ...

The Wireless Instant Messenger (WIM) project implements a portable and interoperable Instant Messaging Client. It is possible to send and receive Instant Messages over a wireless device to services like Jabber, AIM, Yahoo!, MSN, IRC etc. using this client.The project uses Ethernet and Radio communication to achieve this on the hardware side and relies on XMPP/Jabber protocols for messaging and interoperability. It can also be seen as an Ethernet to wireless router for short range communications at speeds up to 1Mbps.WIM has three functional components: WIM Proxy that runs on ...
