Most kits are useless for making projects, they are tailored for kids to learn the basics, with the cheapest sensors and accesories inside.
Just go on ebay and buy whay you need. It will be cheaper and you won't be left with a bunch of cheap stuff you don't need laying around. Get good sensors, a breadboard, patch cables kit for breadboard and sensors, a kit of various resistors, a relay board, and a uno clone. You could also add a display if you think you need one. Then search for examples of code using the gear you got and learn from there.
"We ought never do wrong when people are looking." - Mark Twain
If the whole world smoked a joint at the same time, there would be world peace for at least two hours. Followed by a global food shortage.
