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
