10 Tips to choose a Prototype PCB Assembly Manufacturer

You can lower your costs and get quality circuit boards manufactured in the shortest time possible when you hire a professional prototype PCB manufacturer for the job. Understandably, you are unsure about the factors to consider before outsourcing your PCB for mass production to a PCB prototype manufacturer. That informed the reason why we put […]

CONTACTLESS AUTOMATIC WARDROBE LED LIGHT WITH FADE EFFECT

Contact-less controlled automatic wardrobe light turns on the LED when you open the wardrobe door. Τhe project is based on Hall effect IC including LED driver and tiny magnet. Board doesn’t require any mechanical switch. When magnet is close to the board, LED is off, when you open the wardrobe door magnet goes far from […]

LUX METER MODULE

LUX Meter project has been design to measure the illumination.  Illumination is luminous flux falling on surface area of photo diode.  This illumination converted to corresponding voltage using Op-Amp circuit. SPECIFICATIONS Supply 9 VDC PP3 Battery @ 20 mA  Onboard Photo Diode  Onboard preset for calibration  Range selection via jumper 10mV/LUX, 1mV/LUX, 0.1mV/LUX  Interfacing is […]

SOUND ACTIVATED SWITCH – RELAY

This project is a sound-activated switch. DESCRIPTION Clap switch/Sound-activated switch designed around op-amp, flip-flop, and popular 555 IC. Switch avoids false triggering by using a 2-clap sound. Clapping sound is received by a microphone, the microphone changes the sound wave to an electrical wave which is further amplified by the op-amp. 555 timer IC acts […]

PIR SENSOR

This project is an automatic PIR sensor. DESCRIPTION Project is based on Holtek’s IC HT7610A, which is a CMOS LSI chip designed for use in automatic PIR lamp, flash or buzzer control. It can operate in 3-wire configuration for relay applications.  In our project we have used relay instead of Traic to connect any kind […]
