hi, i ordered them got them pretty fast the look nice, but the dont work well the ambient works but the proximity doesnt ! it cant because of a breakbord/circuit or assembling error of the board. R7 is the needed for the ir led to work! from datasheet a simple bride would be enough but i've choosen a 18Ohm resistor. best regards bernhard
