I´m putting my shopping cart together but I don´t know what IR-Led i should use...
The dealer i´m buying the most stuff from has three different leds, and if you please could recomend one model for the tachometer project...
Here is the three models:

IS658A Fotodiod IR
LED TSAL4400 IR 3 mm Vishay
Does anyone of them work26752675
