Makers and developers that enjoy building projects using the Arduino platform might be interested in a new experimenters kit called the Tsunami, which has been created by Nick Johnson who is based ...

He put the project out on Hackaday.io and also has a video tutorial you can see below. There are five input pins to the chip which lets you connect one analog pin to any one of 32 analog pins.

Now the goal is the same but he has an even more surprising plan, throw the ADC out entirely and sample an analog thermistor using digital IO.

A thermistor can be used to compensate for temperature variation in other components of an electronic circuit. Here is an Arduino experiment with a famed linear active thermistor chip MCP9700A from ...
