Ordered an arduino starter kit from aliexpress Link
The parts list they provide (as a jpg on the order page) is vague and not very descriptive, I've gone through most of the parts and am down to three they did not list.
- Capacitor? -- Looks to be a capacitor, labeled HDX and nothing else, rattles when I shake it.
- Black LED -- I think this is a flame sensor; if it is, what's the difference between this and an infrared receiver (like a 1838B) or photoresistor?
- They also list something as 'a digital control' near the bottom of the list, not sure what that is? Every other part from the list is matched up and I don't see anything different in the first picture (not parts list picture) from what I have received in the order.
