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 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.
