Badges are amazing things. Better when you make your own. I was about to attend the 1st MakerFest at NID, Ahmedabad and thought of taking something unique to the event. Badge was a great option and suited the maker theme of the event. So, sitting down with a pen and paper i drew what it […]

LAPIS Semiconductor, a ROHM Group Company, has recently announced the development of a low power microcontroller that integrates an 8bit low power MCU core, speech synthesis circuit, high efficiency Class D speaker amp, non-volatile memory, and oscillator circuit on a single chip, making audio playback possible by simply connecting to a speaker. The ML610Q304 also
Since you lacked the USB interface in your own Arduino board, it becomes necessary to use a homemade/ready-made USB to Serial Converter Module as an efficient and economical solution. Inexpensive and easy-to-use USB to Serial Converter modules are now widely available, such as one shown here. With the help of this little module you can

I have a device which provides a USB port. If I attach it to a Windows PC it is recognized as a “CP2103 USB to UART Bridge Controller”. According to the device documentation, it should communicate in serial format at 38400bps.I have to talk to this device with a atmega microcontroller. Since the USB pinout
These days I was thinking about a better PIC programmer that can work with Microchip MPLAB IDE software so that I can write my own programs or edit someone else’s programs. I found that there are numerous versions of the famous Microchip PICkit 2 on the web. Some of them are using the original schematic

An h-bridge is a chip that allows DC motors to be run versatile, with bidirectional capability. With an H-bridge, motors can go forward or backward, left or right, up or down, etc, depending on the use of the motor(s) in the circuit. Without a microcontroller, the only way to be able to control an H-bridge

This project uses just three main components to provide forward and reverse control for a single motor. You can easily interface it to an Arduino or any other microcontroller. It’s so simple – you can wire it up “free-form” without a circuit board in about 15 minutes. Features: All parts available at Radio Shack for

Arduino clones are ubiquitous. A quick web search or a look at any electronics hobbyist website will turn up some kind of Arduino-like microcontroller board. Studies have shown that the absolute last thing the world needs is another Arduino clone that adds nothing or very little to existing designs. One might surmise that these are
