Do you mean that the l.e.d. should be run at 20mA? What colour l.e.d. is it?Originally posted by zosh@May 6 2005, 12:20 AM
LED that requiers 5v. 20hm.
and one phototransistor at 5v. 50mh.

sorry, im trying to make a circuit that i found on the internet that calls for the LED and Photosenser to detect when somthing pases between the two. I have found these components on the Jamco catalog. The operating values are hard to interpret and the best I can understand the operating values are as I stated earlier.Originally posted by David Bridgen@May 5 2005, 07:21 PM

Please explain what you want to do with the phototransistor. What is the significance of 5V. What is 50mh?
