  1. One more thing: I plan to use the last ciricuit above. What wattage resistors should I use, and what should Rin's value be?
  2. I will be attempting to make a LED sign, but first I need to do some research. My first question is: What is a shift register, and how does it work?
  3. Like so? This will work without much problem, running a lightbulb? The tungsten filiment is coiled, does that make it an inductive load? Thank you for pointing me to this solution, though.
  4. If you type in the name of the chip and then "datasheet" you'll get: http://www.fairchildsemi.com/ds/NE/NE555.pdf http://www.national.com/ds.cgi/LM/LM341.pdf http://www.jameco.com/wcsstore/Jameco/Products/ProdDS/44581.pdf http://www.daisy-laser.com/products/CD/handset/handset1/irreceiv.pdf
  5. Thank you. I ordered three MOC3041s. Just to be sure, the MOC3041 controls the triac, right?
  6. I am trying to use a triac to replace a broken relay in a circuit I made. A 555 is setup to flash on and off about every second. The positive pulses go to a relay, which controls a 60W 120VAC light bulb. I have bought a triac to replace the relay, but I don't exactly know how to use it. Relay: Coil: SPST 12 volt, 20mA, 250 ohm Contacts 0.5A @ 125 VAC Triac: VRRM: 300V ITRMS: 4A Max IGT(I & III) 30 mA Max VGT 2.5 V Max IH 30 mA Min How can I use this triac? P.S. Do I need to heat sink it?
