The Versatile Development Board for AVR microcontrollers ATmega48/88/168

For those of you here that always involved yourself with the AVR microcontrollers, have you ever wished to build a multipurpose development board that compatible with all type of AVRs microcontrollers, such as ATmega48, 88 or 168? Well, you can simply use this board for testing and debugging embedded programs since it has many built-in peripherals connected to microcontroller. Thus, you can use them without even a further soldering or modification! Ok, I know it sounds unnecessary here, but for those that never ever used any ATmega microcontrollers before, you should know that they have many great features, which as: Easy to adjust I/O, Timers, PWM generators, ADC, RS232, TWI, SPI, Analog Comparator, Osillator, EEPROM etc. The main reasons why you should use these microcontrollers because they’re very versatile, easy to program and having an easy to use interface as well! Since this development board has been specially designed, thus you can apply it to use with ATmega (4kB), Atmega (8kB) or ATmega (16kB). Hope you will enjoy this development board project and until then, see ya! Continue reading

Twinkle Star Ambient Email Notifier

You always expect some of the important emails in your email account, but the waiting process makes you become even more nervous? Kill the nervous today with this stylish twinkle star ambient email notifier. Those materials that needed are: 4d-micro-USB module RGB LED RS-232 port Picaxe 08M COM port Python script Firstly, you need to use a 4d-micro-USB module to provide the power resource. The RGD LED will be controlled by the RS-232 port through the Picaxe 08M. One of the cool feature about this ambient email notifier is you can control the colors and the brightness. How? It’s all can be done by sending execution code to the COM port. Continue reading

Atmega128 development board with MMC/CD slot

It is always good to have handy microcontroller development board where you could test, debug embedded programs. Generally speaking development boards have to be universal and also convenient for interfacing. So usually when people make these tings usually build in some periphery to be ready to use like RS232 interface, MMC/SD slots. So here is one development board with ATmega128 microcontroller which is small but has lots of functionality ready to go like RS232, RS485, ISP, JTAG, MMC/SD connectors. Also it has 62kB of external RAM – so you can run really serious programs without wary. Don’t forget other interfaces like I/O, I2C, SPI, and RTC that are positioned in two additional pin-headers.
