We all know that you can never get too many LEDs. Don’t worry, we’ve got you covered. This is a pack of basic red, yellow, blue and green 5mm LEDs (5 of each) all conveniently packaged in a nice reusable ESD safe bag.

SKU: AF-2831 | Brand: Adafruit

This Photo Transistor Light Sensor is a simple sensor that detects ambient light. It's kind of the opposite of an LED - when light hits the little chip inside, it induces current to flow from the long pin...

SKU: SF-COM-00526 | Brand: SparkFun

The LD1117V33 is a low-dropout (LDO) positive voltage regulator with a fixed 3.3V output. With on-chip trimming providing ±1% output voltage tolerance and built-in current and thermal limiting, it's a reliable choice ...

SKU: SF-SEN-10293 | Brand: SparkFun

A simple piezo element that can be used as both a sensor and a small audio transducer. When flexed or tapped, it generates a voltage that can be read by a microcontroller, making it ideal for knock and vibration detec...

SKU: AF-3522 | Brand: Adafruit

For winding custom coils, or very fine-pitch rework, we always reach for magnet wire. Magnet wire is very very thin (0.1mm diameter!) copper wire with a very thin layer of insulation. It's used for a range of elect...
