Analog Devices
ECJMOUAD597
€10.00
The AD597ARZ is a monolithic temperature Set-point Controller which has been optimized for use at elevated temperatures such as those found in oven control applications. The device cold junction compensates and amplifies a type J or K thermocouple input to derive an internal signal proportional to temperature. The internal signal is then compared with an...

TPIC6595N Shift-Register Display (DIP16)

Texas Instruments
ELC6595
€4.58
shift register chip of the  is used a lot by hobbyis because of its wide availability, good speed and simplicity. Just plug it on an arduino like shown in the tutorials and youi have 8 more outputs, put two and you have 16 more outputs ! (up to a lot of them actually, with only three pins !)

CD4021BE 8bit Shift Register (parallel to serial)

Texas Instruments
ELCD4021B
€1.21
CD4021 is a cascadable 8bit parallel to serial shift register (basically the inverse of the 74hc595). Sometimes you'll end up needing more digital input than the pins on your microcontroller board can readily handle. Using a parallel to serial shift register allows you collect information from 8 or more switches while only using 3 of the pins on your...
