This simple touch sensor project can be used to add a touch switch to your computer. It can detect when you touch a sensor connected to one of the sensor inputs. The project is built based on AVR AT90S2313 (you can replace it with ATtiny2313).

DS1820 Multi Temperature Sensor Readout

August 25, 2010 By: admin Category: AVR, Measurement, Microcontroller, Project No Comments →

The project has ability to measure temperature from up at 8 DS1820 digital temperature sensors all on the same one-wire bus and Log it to a PC using RS232. It can be used to measure temperature at range -55 to +125°C without calibration. This AVR AT90S2313-based project use only 3 wires for all the temperature […]

The MeetingMinder is time reminder for public speaker that give a warning when their speaking time will end. The project is built as indication light tower that has red, green and yellow 360-degree wraparound lights, mounted to a base which houses a large two-digit seven-segment display and the control circuitry. The tower colors indicate “talk” […]

RS232 Frequency Meter and Pulse Generator

March 15, 2010 By: admin Category: AVR, Measurement, Project, Tools No Comments →

This multi purpose project is built around MCU AVR AT90S2313. Besides as Frequency meter, the project can be used as Pulse Generator too (combined counter and frequency meter). It doesn’t have any front panel controls because the user interacts via an RS-232 terminal program at 9600 baud. The user controls reads data via an ASCII […]
