tempriter monitering

Projects General Guidance
1

hi all i would like some help here i am building a battery pack but i would like to keep them as close to the optimal tempriture i am going to split them in to groups and there will be 20 groups but i would like to use some tempriter sensers pumps and solinods so the batterys are all kept around the optinal tempriter.

i and thinking of a tempriture senser on the water in and one on the water out and 2 solinods on the in to let cool or warm water flow.

and was thinking 2 tempriture sensers in the battery pack to moniter the tempriture

i would basicaly like help with this as i am new to arduion and not sure were to start tith this.

i can provide more datials if needed.

and sorry about grammer and spelling i unfortuanterly suffer with dislexia.

The usual advice for projects is to do some pre-work building a number of sketches that just exercise your hardware. For example if you're going to use the popular DS18B20s to measure your temperatures, build a sketch that just reads temperature from the sensor.

Then another one that drives the solenoid - be sure you find the circuit to control it without damaging your Arduino.

Then another that drives your pump - again, you can't just wire it directly to the Arduino.
