IR (Infrared) sensor tuned to 38KHz, perfect for receiving commands  from a TV remote control. Runs at 3V to 5V so it's great for use on the  Raspberry Pi!

To use, connect pin 3 (all the way to the right) to  5V power, pin 2 (middle) to ground and listen on pin 1. It doesn't do  any decoding of the signal, just passes the 'raw data' along.

The Raspberry Pi does not feature an Analog-to-Digital Converter (ADC), so if you want to measure analogue singals, you'll need this 12-Bit ADC!

The Adafruit 4-Channel I2C 12-Bit ADC is a high-precision ADC and features the ADS1015 chip, which provides 12-bit precision at 3300 samples/second over I2C. The chip can be configured as 4 single-ended input channels, or two differential channels. As a nice bonus, it even includes a programmable gain amplifier,with up to x16, to help boost smaller single/differential signals to the full range. We like this ADC because it can run from 2V to 5V power/logic, can measure a large range of signals and its super easy to use. It is a great general purpose 12 bit converter. 

• Wide Supply Range: 2.0V to 5.5V
• Low Current Consumption: Continuous Mode: Only 150µA Single-Shot Mode: Auto Shut-Down
• Programmable Data Rate: 128SPS to 3.3kSPS
• Internal Low-Drift Voltage Reference
• Internal Oscillator
• Internal PGA
• I2C Interface: Pin-Selectable Addresses
• Can run from 2V to 5V power/logic
• Measures a large range of signals and is super easy to use.
• 12-bit precision at 3300 samples/second over I2C.
• Configurable as 4 single-ended input channels, or two differential channels.
• Includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range.
• Breakout Board equipped with ferrites to keep the AVDD and AGND quiet

This Reflective IR Sensor is a simple plastic casing with two elements - an IR LED and an IR phototransistor. You can control the IR LED and turn it on to bounce IR off objects to determine their reflectivity. White & light colored stuff will bounce the light, so you can detect it.
