Concept of Touch LCD LC7981 using ATMega An on-off controller is the simplest form of a temperature control device. The output from the device is either on or off, with no middle state. An on-off controller will switch the output only when the temperature crosses the set-point. For heating control, the output is on when the …

I spent part of an afternoon developing a hardware RSS reader (most of my time was spent on the python side of things). It’s pretty simple and uses an AVR microcontroller connected to a computer via a serial cable. Hardware I am using the Dragon Rider 500 as a development board. This provides all of the hardware …
The BootLoader is a code which executes when a microcontroller is powered ON or reset. It basically sets an environment for the application code to execute. It is the Boot-Loader that sets the hardware and loads the application code from any storage medium or received through external communication and let the application to execute. Thus a Boot-Loader has to …

Well this is not different from the way interfacing the LCD to 8051 or PIC microcontroller. The crystal oscillator will provide the clock to the microcontroller. The capacitors connected to the crystal will act as filters and help the crystal to resonate and oscillates to its parallel resonate mode. The potentiometer which is connected to …
