amansammy Posted November 22, 2012 Report Share Posted November 22, 2012 Hello everyone! This is my first post on this forum.Basically I want to make a simple LED lamp which would take about 9V. For it I want to create an Infrared switch so that I can switch the lamp on with any remote(my TV remote mainly!). I have got an Infrared receiver( TSOP1738 )I also have a 4017 counter, bc547 and bc557 NPN transistors and also common resistors and capacitors.Currently I am eyeing this circuit but this is used to switch on AC Appliances. Can you give a modification for the circuit to switch on/off the led lamp? Or any other circuit for this? Please help. Thank You Quote Link to comment Share on other sites More sharing options...
Hero999 Posted November 22, 2012 Report Share Posted November 22, 2012 How much power does the LED lamp use?Run the TSOP1738 and CD4017 from a 5V regulator and replace the relay with the LED lamp. Quote Link to comment Share on other sites More sharing options...
