Infrared Tracking and Remote Control

Infrared Tracking and Remote Control Tracking, also called position and orientation tracking or position tracking and mapping, is used in Virtual Environments where the orientation and the position of a real physical object is required, for example to interact directly with the 3-D objects rendered by the virtual environment system. An optical tracking system has been [...]

transformerless power supply

transformerless power supply n most non-battery applications, the power to the microcontroller is normally supplied using a wall mounted transformer, which is then rectified, filtered and regulated. In most applications, this method of generating the regulated voltage is cost effective and can be justified. However, there are applications where the PIC12/16/17 is the main controller and low voltage is not required by other [...]

Does anyone know how to make a transformerless power supply that goes from 110V AC at 200mA to 24VDC, if ...

Transformerless Power Supplies: Resistive and Capacitive

Transformerless Power Supplies: Resistive and Capacitive There are several ways to convert an AC voltage at a wall receptacle into the DC voltage required by a microcontroller. Traditionally, this has been done with a transformer and rectifier circuit. There are also switch- ing power supply solutions, however, in applications that involve providing a DC voltage to only the microcontroller and a few [...]

resistor and capacitor data

resistor and capacitor data Electrolytic capacitors take advantage of the ability o some metal oxides to act as an excellent insulator (at voltages) and also form a dielectric material with a ver high dielectric constant ‘K’. Most common electrolytic capacitors use aluminium oxide as the dielectric, but special-purpose and low leakage types generally use Download VN:F [1.2.3_620]please wait…Rating: 10.0/10 (1 vote cast)

Basic circuit analysis

Basic circuit analysis All that is required to analyze any electronic circuit is a thorough understanding of three laws, Ohm’s Law, Kirchhoff’s Voltage Law and Kirchhoff’s Current Law. However, before these laws can be mastered, the student needs to understand the basic units of electricity (voltage and current) and the concept of resistance.
