Fingerprint Sensor AS608 - A Beginner's Guide
One touch can replace keys. This project uses an optical fingerprint sensor to enroll users and then grant access with a quick scan.
read tutorial →Fire up your engines because these are the hot-rods of toggle switches! Equipped with an aerodynamic yellow protective casing, and a yellow LED at the tip of the switch, this Yellow LED Toggle Switch is sure to add some flair (and flare!) to your project.
Often seen on control panels, now you can mimic a racing car, fighter jet, submarine status panel, factory controls, or anything really. They will control virtually any accessory you can throw at them, with a rated voltage of 12V max, the LED lights up at 3V so you can use it with lower voltages too. They say "20 A" on the side but we recommend 1-2A max.
Since there's an LED inside, but only 3 pin, they're a little different to wire than most toggle switches.
The protective cover will automatically turn the switch off when flipped closed, but you can simply remove it if it isn't desired.
