 | | A fast light sensor?

|
Ummm, Hi all I'm looking for a circuit that will interface a photo transistor or a photo diode to a digital input. I tried a photocell in an analog port but it's too slow, I want to use a *visible* light pulse as an accurate trigger: ie. input (...) (26 years ago, 20-Jan-99, to lugnet.robotics.handyboard)

Dear Mr Fred Martin/friends, Thank you for giving the site of the new library files.We started IC properly today.It gave NO 'synchronizing with board' errors. We input 1 + 2; and it gave the proper result.However when 123 * 2; was entered at the C> (...) (26 years ago, 19-Jan-99, to lugnet.robotics.handyboard)

Handy-folk, I recently discovered that there is an experimental version of Java for the 68HC11 microcontroller. Cool! It has been in field testing since June, and looks promising. The developers tell me that a beta version should be released in a (...) (26 years ago, 19-Jan-99, to lugnet.robotics.handyboard)

i am unable to reproduce the problem. perhaps comms between IC and your board are still unreliable. try writing a program that repeatedly prints to the LCD screen the result of 123 * 2. my guess is that it will work perfectly. also, make sure you (...)

I remember the Basic Stamp "POT" command which is used to read the position of a pot using a digital port. The Basic Stamps are made from PIC microcontrollers and the digital ports are bidirectional. That is they may be used as digital inputs or (...) (26 years ago, 19-Jan-99, to lugnet.robotics.handyboard)
