  1. Remote AC Power Control by Android Application with LCD Display

  2. Remote AC Power Control by Android Application with LCD Display Introduction • The project is designed to control AC power to a load by using firing angle control of thyristor. Efficiency of such power control is very high compared to any other method. Remote operation is achieved by any smart-phone/Tablet etc., with Android OS, upon a GUI (Graphical User Interface) based touch screen operation. The project uses zero crossing point of the waveform which is detected by a comparator whose output is then fed to the microcontroller. http://www.edgefxkits.com/

  4. Remote AC Power Control by Android Application with LCD Display Hardware Requirements • 8051 series Microcontroller • LM358 • Opto isolators • SCRs • Push Button • Transformer • Diodes • Voltage Regulator • Resistors • Capacitors • Crystal • Lamp • Bluetooth Device http://www.edgefxkits.com/

  5. Remote AC Power Control by Android Application with LCD Display Software Requirements • Keil compiler Languages: • Embedded C or Assembly • Android Application. http://www.edgefxkits.com/

  6. Remote AC Power Control by Android Application with LCD Display Embedded Systems • A combination of hardware and software which together form a component of a larger machine. • An example of an embedded system is a microprocessor that controls an automobile engine. • An embedded system is designed to run on its own without human intervention, and may be required to respond to events in real time. http://www.edgefxkits.com/

  10. Remote AC Power Control by Android Application with LCD Display Liquid Crystal Display (LCD) • Most common LCDs connected to the microcontrollers are 16x2 and 20x2 displays. • This means 16 characters per line by 2 lines and 20 characters per line by 2 lines, respectively. • The standard is referred to as HD44780U • It refers to the controller chip which receives data from an external source (and communicates directly with the LCD. http://www.edgefxkits.com/
