The following file is an application note describing the two stages of an electronic ballast for a 250 W HID metal halide lamp. The components include. The application note outlines a two-stage electronic ballast designed specifically for a 250 W high-intensity...

Electronic combination lock with PIC

This is my electronic combination lock to use with an outdoor gate. The functionality is implemented in software. It turns on a relay (usually to open a door) for a few seconds if someone enters the valid code. This relay...

Universal PIC-EEPROM programmer

This is a JENS MADSEN project I've built to program my PIC and EEPROM (16xXXX AND 12CXXX AND 24CXX). I use it with IC-Prog; it is little, simple to build, cheap, and gives few bugs. More: When I built it,...

Simple flower circuit

The circuit includes resistors Rp1 to Rp13, which serve dual purposes: they scale the resistance for the keyboard and function as timing resistors for the oscillator. Capacitor C2 acts as a wide discharge capacitor, while switches S1 to S13 represent...

parallel PIC

The purpose of this project is to construct a computer that utilizes the combined computational power of multiple microcontrollers (MCUs). All MCUs collaborate to solve a single problem. This computer is classified as a parallel processing machine, and the algorithms...

Industrial Building Automation System (IBAS) - 4

The two optical sensors will provide a count of individuals to the microcontroller, which will relay this value to MCU-II. The microcontroller will detect the entrance of any person through high-to-low pulse transitions on input pins A3 and A4. The circuit...
