First part of the plan
So, this is the plan:
A MCU, a temperature sensor, a combined temperature and humidity sensor, somewhere to show the readings and some keys to press.
To have a logger, let’s add a RTC and a SD card reader.
Even if I have a development board with a 90S2313 (called Attiny2313 now) somewhere, it will not be good enough for the logger function. Not enough Flash.
So, after surfing round I decided for an Arudino Nano. One reason is that I found a place that sells it for a good price. That it has USB port is another reason.
My current want to shop list….
