Series resistors are a simple way to stabilize the LED current, but energy is wasted in the resistor. Miniature indicator LEDs are normally driven from low voltage DC via a current-limiting resistor. Currents of 2 mA, 10 mA and 20 mA are common. Sub-mA indicators may be made by driving ultrabright LEDs at very low current. Efficiency tends to reduce at low currents, but indicators running on 100 μA are still practical. cottage row statesboro gaWeb4 Likes, 0 Comments - Flawless Vape Shop (@thereal_fvs) on Instagram: "SMOK Vape Pen V2 Kit is a compact brand-new multifunctional AIO vape pen kit that brings the ... breathing sleeping catWebIn this video, I challenged Richard from Video Game Restoration to repair a broken Game Boy and then turn it into the ultimate Game Boy by upgrading the screen and installing a rechargeable battery. breathing sleepWebIf you want to learn about what these materials are check out these wikipedia entries: LEDs Power supply Resistors Materials: LEDs - I basically just reached into the drawer at Radioshack and pulled out anything that wasn't more than $1 or $2 per LED.
