 | | running 2 IR
|
|
I want to be able to run 2 or 3 IR xmitters from the single output on the HB with no additional hardware. Is there any problem with hooking two or 3 IR transmitters to the ground of the IR output and running the +5v from digital outputs. Then switch (...)

Certainly the voltage follower will work. But I had a similar problem adjusting the sensitvity of a photocell that I solved by paralleling a pullup resistor of my own to get the proper impedance. You might try putting a 1 ohm (yep, thats one NOT 1k) (...) (27 years ago, 5-Apr-97, to lugnet.robotics.handyboard)
