So next update in 3+ weeks, if delivery times are anything like we get in Ireland from AlieExpress. Although, to be fair - I have never been let down by them.
@WeeBoWhat IR receiver are you using & what is your circuit/code like. ?
These are cheap IR receivers (by price at least ~34 cents). I haven't used them.According to this datasheet:http://www.hyzt.com/manager/upimg/200987165540.pdfThere are some external - 2x capacitors & 2xresistors required(or suggested) for the IR recevier circuit.It was hard to read the DS, but it seems to suggest that the modulation frequency is centered on 38kHz, which should be OK. But unlike the earlier post it doesn't give any details on attenuation at other frequencies. (= low quality??)I also saw a post on another forum, where somebody had left out a resistor when using a FET to drive this particular LED and which resulted in lots of interference. (can't remember details sorry)
