#120834 - AC control Responding to: ???'s previous message |
Does the lamp light if you apply a steady 5 volts to the opto ?
If it does check the duration of the pulse output from the uC. If the pulse is too short or too infrequent you will not be able to see a filiment lamp respond. If the lamp does not light with a steady 5 volts check that you have the polarity correct on the triac (MT1-MT2) Good luck Bruce |
