This project is a lights effects board using common bulbs.

Description

This project provides some lighting effect by the blinking pattern of the bulbs connected at its output. Up to 8 Bulbs can be connected in between connector CN2 to CN9 and AC power to control them should be connected at Connector CN10. DC Power should be applied at Connector CN11 in accordance with the polarity marked on this connector. Care should be taken while using this it as it contains Main Power on the board.

We can change the Blink pattern by the press of the SET switch and change the blinking speed by the press of the UP and DOWN keys on the PCB. Fuse F1 will protect the Kit from any possible short circuit and excess current flowing through it.

Features:

  • Microcontroller based design for greater flexibility and ease of control
  • Triac based switching of loads connected to the circuit
  • Industry standard isolation with the help of Opto enabled Triac Control
  • Fuse protection for AC output
  • SUPPLY 9-12V DC & 230V AC
  • LOAD-100W max on each output
  • Simple and easy to use 3 tactile switch enabled control of the project
  • PBT type connector for connecting supply (AC/DC) and TRIAC output on the PCB
  • Onboard regulator for regulated supply to the project
  • Diode protection for reverse polarity connection of DC supply to the PCB
  • Four mounting holes of 3.2 mm each
  • PCB dimensions 86 mm x 173 mm

    This project is mainly used with incandescent lamps and it seems that there is some leakage current through the TRIAC. You may try another TRIAC with lower “Off-state leakage current”

      You may try MAC12DG from ON Semiconductor which has 1/10th of leakage current of BT136
