dew heater kit for telescope

hi everyone, i am so green to electronic but hey i'm going to give it a go, i was just wondering if i could get a little help.

i'm trying to make a dew heater controller for my telescope this is what i found on the net

https://www.jaycar.com.au/diy-telescope-dew-heater

but i cant really see where all those wires are going to, any help would be appreciated.

Each individual component and it's wiring is shown in separate schematics with the correct pins identified. What don't you understand?

Do you have all the component in hand?

Paul

well i am pretty green at this , have all components, i dont know how to read schematics.
for example; DHT11 is the thermostat, gnd well i know where that is on the uno board because it says it, as for D3 and SV it hasn't got that on the board

My Arduino board has those. Bet yours does to.

PS. See, you can read schematics!

So is this correct

5V (5 Volts), not "SV".

Great tutorial on how to read schematic diagrams.

Hi
Welcome to the forum.

I hope you realize you will have to solder those connections.

Soldiering is the easy bit.
Any advise for putting it together tom?

Hi,
As an Australian I am very disappointing with the standard of the instructions for that project.

I fact I would say it has no instructions, just a "here is what it looks like and here are the components".

I am going to say it, Even A Fritzy Diagram would have helped.

I have contacted JayCar via their contact page expressing my disappointment.
I will see what I can do for you.

Hi tom it does have schematics

But what i cant follow is the the proto board

I would expect a schematic, not a scattering of diagrams.. lol

I think the intent was to show each device/circuit can and should be implemented and tested individually.

Thanks heaps Tom

I wouldn't recommend the DHT11 for dew point: this implies you expect the humidity to go to (near) 100%, and the DHT11 measure no more than 80% or so. You'll need at least the DHT22, or even better a BME280.

I was just wondering, you guys sound pretty smart, well smater then me anyways, would you be able to check the code for me.
