Large Dancing Robot Build a large dancing robot. This was supposed to be a walking robot, but it more kinda beebopped around. video on last step. Build a Prototype First, The _Prototype_: Before you make a large, high power robot, it’s good to make a smaller scale prototype. I made a simple walking robot using […]

alculator with Pic 16f877 microcontroller is a comprehensive project. Comprehensive in the way that Code is lengthy and logical. It covers all the aspects of programming and interfacing of 16×2 lcd and 4×4 keypad with pic Microcontrollers. So you should be good in programming, if you are going to look at the code and you […]

Learning the assembler language is one of the essential skills that still required in the embedded system, although the major drawback using the assembler language is; its required more learning curve time compared to the higher level language but once you acquainted with one type of microcontroller family such as 8-bit 8 pins Microchip PIC […]

This PIC microcontroller based RC driver is able to control 4 RC Servo by on board independent 4 potentiometer , 4X3PIN header for RC servo interface, screw terminal for supply input, on board power LED, optional 4X3PIN header connector for external potentiometer. Features Microcontroller based design for greater flexibility and ease of control Individual servo […]

Gas sensing techniques are continually being investigated to improve selectivity and sensitivity of identifying different types of gases. There are resistive gas sensors, quartz crystal microbalance, direct thermoelectric, electrochemical cell and other exotic types such as MEMS-tunable Fabry-Perot filter spectral sensors with lead-selenide detector and pulsed broadband infrared emitter light source. The ams sensor is […]

Up to 120 TMC messages are stored in memory. Auto/manual TMC message scrolling. GPS position locator/follower optional. Map navigation with  mouse sensor and/or micro joystick. Map zoom 10km to […]

Have you ever thought that most of our perception about the robot is based on the Hollywood movie! The famous 3CPO and R2D2 from Star Wars until the little cute garbage compacting robot named WALL-E; all of these machines are example of our dreams or should I say our quest to what we all think […]

As EDN’s Design Ideas editor, I see a range of design submissions, from good, to not so good. A recent DI I turned down for several reasons included a high-side current sense circuit with implementation problems. This got me thinking about the different ways to accomplish current sensing on a voltage rail. At their heart, […]

This is my first simple PIC program. It will flash an LED continuously at approximately 1Hz. It is a very simple loop that delays for 500 milliseconds (half a second) with the LED on, and then delays for 500ms with the LED off. Thus, the LED flashes at 1 Hz! The schematic for this circuit […]

Description The MAX9626/MAX9627/MAX9628 are low-noise, low-distortion, and high-bandwidth differential amplifier/ADC drivers for use in applications from DC to 1.35GHz. The exceptional low input-referred noise and low distortion make these parts an excellent solution to drive high-speed 12-bit to 16-bit pipeline ADCs. The output common mode is set through the VOCM input pin, thus eliminating the […]
