I got a sample of a RGB Led (Red Green Blue Light Emitting Diode). So, I decided to make something fun out of it. Using an 8-pin AVR microcontroller, ATtiny45, I made a simple prototype to control the RGB Led using PWM or Pulse Width Modulation.
Then, I put the prototype …

What is an interrupt?
An interrupt is an asynchronous signal that needs attention. An interrupt stops the CPU of a microcontroller, leaving the tasks that it is currently doing, to give attention to the interrupt signal. Once the attention has been given to the interrupt signal, the CPU goes back to its unaccomplished …
USB has established itself as the new standard for connectivity. That is why USB connectivity has become the “holy grail” of most embedded applications.
Well, let me get straight to the point. If you want to start developing projects with USB interface, you want to have the proper development tools. To have the tools that …

What is UART?
UART stands for Universal Asynchronous Receiver/Transmitter. As its name implies, it is universal. It can be used to establish a communication between a microcontroller and another device – microcontroller, USB controller, Bluetooth modules, GSM modules, GPS modules, personal computers, etc.
Want to learn real digital hardware design? You might want to consider Field Programmable Grid Arrays or FPGAs. There are a lot of FPGA learning kits available today. Some are specially designed to target developments of commercial projects which are, of course, very expensive. Some are a little bit price friendly …
