How to interface CMOS camera and microcontroller? well, Iñaki Navarro Oiza had made great microcontroller project about it. The camera called c3088 uses a CMOS image sensor OV6620 from Omnivision. To communicate between microcontroller and camera he use I2C protocol. As processor it used Atmel AVR ATmega16."The aim of this project is the development and construction of an interface between a CMOS camera and a computer. This interface allows a user to get images from the camera, to change some of the properties of the camera as brightness, luminance, etc ...

News from Atmel"AT91SAM9XE 32-bit Microcontrollers Integrate Flash, SRAM and Boot ROM with USB Host/Device, Ethernet, Multiple Serial Interfaces and DMA for Maximum Performance, Connectivity, and Data BandwidthAtmel Corporation, announced today the sampling of the AT91SAM9XE-series, the first generation of monolithic ARM9-based Flash microcontrollers that combines a 200-MIPS ARM926EJ-S™ processor core with up to 512K bytes of high-performance on-chip Flash. The new device offers an unrivalled combination of performance and functionality on a single chip, making these Flash microcontrollers ideal for space-constrained applications where high performance is required.Smooth migration from ...

About Microcontroller now give mobile version for its content. You can access our Microcontroller Project weblog via your Mobile device like PDA or Mobile phone at http://abmicro.mofuse.mobi. We know that there is need more improvemnet to our new mobile weblog. But, We hope with about microcontroller mobile version you will never miss for our new post.

Using remote control make our work more easier. like turn off Air conditioner, change channel TV, play your home theater and more. There are many type of remote control like Infrared, Radio Frequency, SMS and more. To control device behind the wall like garage door you can only use Radio Frequency remote control. Because the other can not bypass the wall.Here is RF Remote control using microcontroller created by serasidis. There are two part in this electronic project : transmitter and receiver. The transmitter is constituted by AT90S2323 microcontroller and ...

When you need connect your Microcontroller Project to COM port in PC you need RS 232 converter. There are many chip to solve the problem like MAX232, DS275 etc. But if you need simple and chep for RS 232 converter, i though this circuit will be usefull for you. The design made by Wichit Sirichote."A circuit diagram shown above was used two small signal transistor, NPN and PNP transistors. Dash line separate transmitter and receiver circuit. For those who need only transmitter circuit can use above circuit (and GND (5) ...

Another cool microcontroller project from jesper. Counter measurer using microcontroller AT 90S2313, you can use ATtiny 2313 to replace it. It could be a simple digital counter count up at 35-40Mhz.The software written in C code."It uses only 4 chips - 3 HC TTL's and an Atmel At90S2313 microcontroller. It has a 5 digit LED display plus one used as a band indicator. Even with the LED display, the current consumption is less than 50 mA. It counts up to at least 52 MHz. I couldn't find any signal source ...

Tempereature controller made for monitoring temperature and control the heater. This microcontroller project created by jesper.It's based on an Microcontroller AVR AT90S2313 and a Dallas DS1621 Digital Thermometer. The temperature is displayed on a dual 7-segment display, and two buttons are used for setting parameters. A high current relay switches the heating element.The project use C language to programm it, will make everything more easier. A 4 MHz ceramic resonator is used for clocking the 2313. "A fun little construction and a good way to learn about the DS1621" Jesper ...
