I tried 5 IR receivers in the same circuit to see which worked best. Using a circuit like in the application notes except it uses a .1 microfared capacitor, the tsop2438 and tsop1138 receivers work fine. But the tsop34838, tsop38238 and tsop4838 don't seem to work at all.
The recommended cap is 4.7 microfareds. Could the smaller cap be the problem? Should all receivers work with the same circuit?
I also noticed that the tsop1138 gets inserted backwards to how i would expect. Could inserting the receiver backwards fry it?
The receivers that don't work have a larger operating voltage: 2.5-5.5V. The working receivers operating voltage is 4.5-5.5, They are being powered by a USB powered Ardweeny's gnd and + pins. Could the different range be an issue? I assumed the wider range was an advantage.
