Hello everyone,
I've Googled the issue and have stumbled into this forum! Please be kind.
My issue:
I can find circuits easily enough online, but they range anywhere from 1.5 V - 12V Vcc. If I wanted that circuit, but I am using a different power supply (5V USB adaptor in my case) how would I come about changing the components? I remember Ohm's law just barely, but it becomes very difficult, if not impossible for me to decipher and re-engineer after leaving electronics for so long.
What I want:
I'm a model-maker looking to work with a few blinkie lights and sounds. Currently, I'm looking to make a LED Chaser circuit, flashers and strobes. Pretty easy fare, as I remember doing this stuff in Grade 10.
Background:
I took electronics in high school, from 9 - 12, but that was many years ago. I feel pretty old now... in any case, unfortunately, I threw out all of my notes so I have to go from what I remember.
One of my friends suggested that I go to a microcontroller, but the set up is very confusing for me, and it seems to be a needless headache and expense at this time. He says that MCs are very flexible and can do various interesting effects for my projects -- but still.
I do not have a brick-and-mortar store within driving distance, so I have to turn to the Internet for components. I'm stumped right now, as I have no idea which components to order as I don't have a schematic to work from right now. I need caps, resistors, LEDs, 555s and maybe a 4017 chip or two. But their values; that I have no idea.
Please give me your feedback!
