Some of the fruit and vegetables we eat can be used to make electricity. The electrolytes in many fruit and vegetables, together with electrodes made of various metals can be used to make primary cells. One of the most easily available vegetable, the ubiquitous lemon can be used to make a fruit cell together with […]

When working with discrete JFETs, designers may need to accommodate a large variation in device parameters for a given transistor type. A square-law equation is usually used as an approximate model for the drain-current characteristic of the JFET: ID=β(VGS−VP)2, where ID is the drain current, VGS is the gate-to-source voltage, β is the transconductance parameter, […]

Aluminum Capacitor Pitfalls Aluminum electrolytic capacitors remain a popular choice in power supplies due to their low cost. However, they have limited life and are sensitive to both hot and cold temperature extremes. Aluminum electrolytic capacitors are constructed with foils placed on opposite sides of paper saturated with an electrolyte. This electrolyte evaporates over the […]

Ever wondered how the TV and monitor displays you use every day work? The TFT-LCD manufacturing process consists of a set of processes for producing TFT, color filtering, cell, module and others. LG Display Newsroom gives a detailed, but easy to follow explanation of the entire steps below. Close Look at the Thin Film Translator […]

Tiny Board has been designed around LV8772 IC from On-Semi. This driver is capable of micro-step drive and supports 4W 1-2 phase excitation. It has Low on Resistance with motor current selectable in four steps. The board is equipped with unusual condition warning LED and input Pulse Monitor LED. It is most suitable for the […]

This is a simple application of internal 10-bit ADC(analog to digital  converter) of PIC16F676 microcontroller.you can use this  circuit  to measure  up to 30 v dc. the possible  applications are on bench top power supply or as a panel meter in various system. Circuit description              MICROCHIP’S PIC16F676 is the heart and brain […]

We described simple method, how to drive modellers servo. Today, we are going to try to drive this servo from potentiometer connected to TR module ADC. It is reaction to forum thread where is discussion about airplane model control possibility. We are going to use redesigned ADC usage example (sensor module source code) in this […]

Microchip Technology have announced a computer peripheral 6” touchpad which it claims is the first able to resolve 2D multi-touch and free-space 3D gestures. To detect gestures up to a distance of 70 mm from the pad surface Microchip have used their MGC3130 single-chip gesture recognition and motion tracking controller released in 2012. It works on […]

16-Bit I2C-Bus LED Dimmer This project is devised for LED dimming using NXP Semiconductors’ PCA9532 16-Bit I2C-Bus LED dimmer. A lot of solid-state lighting applications require control over the emitted intensity of light for both functional and aesthetic requirements. Some of these applications also require a full dimming capability from fully ON to fully OFF. […]

DC Motor and L293D We can’t drive a DC Motor (depends) directly with a Microcontroller, as DC Motors requires high current and high voltage than a Microcontroller can handle. Microcontrollers usually operates at +5 or +3.3V supply and it I/O pin can provide only up to 25mA current. Commonly used DC Motors requires 12V supply […]
