Hello all,
I am trying to build a simple circuit that will pulse an LED diode with a specific current at a specific frequency. I am currently trying to use a 555 with a resistor feedback loop.
The circuit begins at the Labview Wave Generator which sends a signal through a resistor. The pulse then splits the pulse to the input of the 555 and the feedback resistor which recombine on the output side and proceed through another resistor into the diode. I am using a 9V battery as the VDD and GND.
Currently it will pulse at the correct frequency, but I can't seem to get the correct current out.
Please let me know if you can help with this circuit or if you can suggest a better circuit to achieve my goal.
Thank you
