One of the commonly asked questions when we move to the bigger and powerful 16-bit microcontroller is do we really need it? As the 8-bit microcontroller is already suite almost all of our needs from a simple blinking LED to more sophisticated embedded application such as robotics. Despite the debate whether to use the 8-Bit […]

It wouldn’t go. I messed about changing component values for while, then decided to actually try to understand the circuit. Now for an oscillator to work, we need an amplifier with a gain of greater than 1, and a phase shift of 360 degrees to get positive feedback. The circuit above is an amplifier, with […]

Introduction External circuit converts bass beat of music into pulses.The motor is controlled by them. If theres bass beat recognised then the motor rotates one direction(in full stepping) for a predefined time then stops. If the second beat comes in then it rotates again for the same time and so on.There is a random number […]

There’s a new high-density class of CXA arrays from Cree that doubles the lumen density for next-gen LED spotlights. The CXA 1520 is the first HD Array announced under the breakthrough technology. It enables lighting manufacturers to create products that deliver the same intensity and light quality as 39W ceramic metal halide (CMH) at up […]

Designing a simple and yet functional Line Follower Robot (LFR) is always a fascinating and challenging subject to be learned, the LFR actually could be implemented in many ways start from a simple two transistors to a sophisticated PID (Proportional, Integrate and Differential) which take advantage of the programmable feature of microcontroller to calculate the […]

On the top image you can see the first Memtype prototype next to the first version. The prototype was done using a Digispark board and was modified to insert a 4 way switch. On the bottom, the latest (OSHPark made) version with SMD joystick and two LED is shown. FEATURES: Encrypted storage using NOEKEON implemented […]

When I designed the “YAP” for the “YAP” PICMicro programmer presented in “Programming and Customizing the PIC Microcontroller”, I felt that the serial interface provided in “execution mode” of the programmer would be very useful for people developing their own software. With this interface, the user could input new values into the PICMicro application or […]

Hi there, today I’m gonna to give you some PIC interfacing circuit. We have already seen how to connect LCD display to PIC MCU which has a great role in electronic display board industry. By the way how do we interface 7 segment displays to PIC microcontroller? Some of you guys may already familiar with […]

When Texas Instruments (TI) introduced their new value line 16-bit microcontroller complete with the programmer and development board named MSP430 Value Line LaunchPad in the mid of 2010 for only USD 4.30 include the shipping cost, this make it as the cheapest programmer and development board platform that you could ever find in the market. […]

Openbench Logic Sniffer is an open source logic analyzer. It’s designed to support the SUMP logic analyzer software at the lowest possible cost. Download the source and design files from the Gadget Factory project page. This project started in the comments on a post. Initial circuit design, PCB layout, development, and testing continued in the […]
