My IR receiver module from Banggood bangged after first run - it just ceased working. The next new one will take weeks to arrive, but the show must go on.... so decided to find temporary solution, and it worked :). I googled, and found that mostly it is mentioned that normal photo-transistor itself cannot be used as an IR receiver because it does not have inbuilt amplifier. There was a photo-transistor BPW 77NB and standard NPN amplifier transistor PN2222A in the components box, so decided to go with this trial experiment and it worked...in the first attempt. The range is obviously not very long (around 30-35 cm ) like standard TSOP IR receiver (few meters). But at least I could continue to work on the main project until new IR receiver arrives :)Let us see how to make it work...
Hello Everyone!This is my first Instructable so please bare with me. Any comments and suggestions will be greatly appreciated! I wanted to share my project in the hopes it can simplify your research, planning, design and execution. Like with any project, it's always a good idea to research anything and everything about the subject matter in order to grasp the different technologies available and challenges you might face.
