UT387B - Metal, wire and wood detector by Uni-T

TSL2561 luminosity sensor is an advanced digital light sensor, ideal for use in a wide range of light situations. Compared to low cost CdS cells, this sensor is more precise, allowing for exact lux calculations and can be configured for different gain/timing ranges to detect light ranges from up to 0.1 - 40,000+ Lux on the fly. Adafruit 439

Adafruit 286 - LoL Shield GREEN - A charlieplexed LED matrix kit for Arduino - 1.5

Adafruit 280 - USB/DC Lithium Polymer battery charger 5-12V - 3.7/4.2v cells

Adafruit 274 - LoL Shield RED - A charlieplexed LED matrix kit for the Arduino - 1.5

This is a great battery-backed real time clock (RTC) that allows your microcontroller project to keep track of time even if it is reprogrammed, or if the power is lost. Perfect for datalogging, clock-building, time stamping, timers and alarms, etc. Adafruit 264

4-digit 7-segment display with MAX7219 driver chip. Adafruit 1268

Inside are two sensors, one is a classic 3-axis accelerometer, which can tell you which direction is down towards the Earth or how fast the board is accelerating in 3D space. The other is a magnetometer that can sense where the strongest magnetic force is coming from, generally used to detect magnetic north. Adafruit 1247
