I should realize a Wheatstone bridge with its amplifier to be connected to arduino for the thermoresistors
Some of you have any scheme or how to make it able to explain



Review the sites of Analog Devices, Microchip, Linear Technologies for the ADCs they offer - these (16+ bit) ADCs typically include a drawing in the data sheet on how to use these chips with a Wheatstone bridge - especially when you're dealing with very high-resolution ADCs like the LTC2485, for example.

Theoretically, you could also use an op-amp with an Arduino to build a crude wheatstone bridge. However, I wouldn't simply because the resolution of the ADC inside the Arduino isn't that great (about 10 bits).
