Hello. I have two electonics projects that I would like to attempt to dip my feet into things. I am in the process of doing an order online for parts but I was hoping you guys could help me make sure I'm getting everything I need?
They are simple circuts. Both run off a watch battery.
The first is two Adafruit Sequin ( https://www.mouser.ca/ProductDetail/485-1758/ ) LEDs run off a watch battery.
The second is a single Bar Array LED ( https://www.mouser.ca/ProductDetail/630-HLMP-2300/ ) run off a watch battery.
I am also building a Ghostbusters trap, but I am using different LEDs than the plans. I am using following based on the recommendation of another person ( https://www.mouser.ca/ProductDetail/485-2860/ ). He mentioned that he used a 470 ohm resistor on the first LED to protect it. Is this appropriate? ( https://www.mouser.ca/ProductDetail/603-CFR-25JT-52-470R/)
My question is, do I need any resistors for these or am I good?
