Description Features: Measures temperatures from -55°C to +125°C Three LED’s to indicate in what range the temparature is. User definable thermostat with high and low settings Output via a relay to control a heater element or a blower fan (or something else) Power supply ………………….4.5 to 5.5 VDC Power consumption ………..15mA This circuit uses a […]

Description With this circuit you can drive a unipolar stepper motor. It operates in full step mode. You can get a stepper motor from an old 5.25 disk drive. The AVR attiny2313 micro controller controls the pulses for the stepper motor. The pulses are amplified by the ULN2003 driver. The driver accepts 5V inputs, the […]

San Jose, CA (Vocus/PRWEB) January 11, 2011 Chip making industry, which has become an indispensable part of modern electronics with almost every man-made electronic device being integrated with an embedded microchip or integrated circuit (IC), has however suffered the worst in 2008 and 2009 due to the economic recession. SoC, an important part of the […]

Description This is a peripheral board with 4 relais, rated at 5A/250V each. The board has a ML10 output connector for connection with the AT2313 Project board. It has also 4 LED’s for indication which relais is switched on. Hardware The circuit is simple, it consists of no more then an ML10 connector, a ULN2803A, […]

This project displays the temperature on an LCD display with an resolution of 0.06degrees. DS1820 is used for sensing the temperature. It can measure temperature range from -55deg to +125deg. But i take care of only the possitive temperature. There are 3 switches to change the alarm temperature, the user can increment the Alarm temperature […]

Description The PCF8583 is a clock/calendar circuit based on a 2048-bit static CMOS RAM organized as 256 words by 8 bits. Addresses and data are transferred serially via the two-line bidirectional I2C-bus. The built-in word address register is incremented automatically after each written or read data byte. Address pin A0 is used for programming the […]

Here’s an another project, which makes an Scrolling LED display. Here 64 leds which are connected to an Matrix display. The Anodes are drived through an Driver IC UDN2981 and the cathodes are drived through ULN2803. The Atmega8515 is used in this project to control the display. The microcontroller is programmed with Bascom AVR. Circuit […]

This project is used to automate the home appliances through Bluetooth enabled PC. You can use the USB Bluetooth at the PC side and an Serail Bluetooth converter is used at the microcontroller side. The sparkfun bluetooth module is used here, but you can use any serial bluetooth module which supports SPP profile. Atmega8 microcontroller […]

Here’s an another project with LED. It can show different patterns. There are 11 channels of LED. Circuit Diagram For more Detail: Multipattern Running light using ATtiny2313 microcontroller
