G'day all.
I'm a total novice to electronics. I'm a software developer, but not C/C++ (C#).
I'd like to try create something and am working out what (As in, I have no idea, but to make a light come on would be a great start!)
My plan is the typical weather station.
I've ordered a Freenove clone of the Arduino Uno R3. It comes with some items, some of which will be useful in my rather (for you guys) boring quest.
My goal is the have
Red LED x4
Green LED x4
Blue LED x4
RGB LED x 1
220Ω Resistor
1kΩ Resistor
10kΩ Resistor
Potentiometer
Push Button
1N4001 Diode
NPN Transistor
PNP Transistor
2xAA Battery Holder
L293D
74HC595
Active Buzzer
Passive Buzzer
Thermistor
Photoresistor
Relay
Motor
Servo
HC-SR04 ultrasonic ranging module
LCD1602 Display Module
RC522 RFID module
IC Card
Key Fob
Breadboard
Jumper Wire M/M
Jumper Wire F/M
Resistor Color Code Card
I think I need to order a BME280 which will supply my temperature, humidity and air pressure values.
From what I have read, that works well with the arduino, and is pretty accurate.
It seems I can get one in either 5v or 3.3v - Not sure which to go for. I'm not sure.
It also seems you can't get them with the header pins soldered on. Bad for me, as I don't know how to solder. Anyone aware of a cheap supplier of the BME280 with header pins soldered?
Is there anything else I may need to achieve my stage 1 goal?
(Stage two would be to somehow be able to get the data somehow onto a webpage, but that's wifi... and a whole load of things I don't think I'm ready for)
Any help and advice would be great. I'm really new. Trying to work out why you need a resister for a LED. That's how green I am.

My goal is the have
- the Temperature, Air Pressure and Humidity displayed on the LCD
- a potentiometer connected where I can set a 'Warning' temperature value
- which will light a red LED lit when at or above the warning temp
- a green LED is lit when the temp is below the warning temp
