Development of a stand for measuring the characteristics of the camera. Where to begin?

Question

Arduino

It is necessary to develop a circuit that can heat a nichrome wire sequentially by 1 degree Celsius, as well as change the illumination by changing the brightness of 2 lamps / diodes. This circuit includes an Atmega microcontroller. Where to start development, what resources to get information from, maybe someone was doing something similar.

Answer 1

judging by the question, you need to start with the basics of circuitry ...
then the temperature sensor.
brightness sensor
control of a powerful load ...
well, a lot of little things that will come up during development and maintenance.

Answer 2

with such questions, you first need to go to a nursery> kindergarten> school (at least 8 classes)
and not engage in development

Answer 3

It’s worth starting with a clear description of what it’s all about.
The wire is different ... 1 cm or 1 meter are two different things.
How accurately do you need to control the temperature, how exactly to control the temperature? What is the temperature range? 25-30 degrees or up to a thousand?
As a first approximation, you will need a power source that is enough to heat the wire, a mosfet that will regulate the heating, a thermocouple that will read the temperature.
With lamps and diodes, to begin with, decide what we are talking about, about brightness or all the same illumination? This kagba is also a different concept and is measured in different ways.
