Hello. I'm new to the electronics hobby (background is as a physician and wannabe software developer).

I received a Chinese electronics kit as a kit from my wife with tons of components in it. I've figured out what all of the pieces except for the three. Could anyone help me to work out what they are?

 

hi,
The first photo is a bread board plug in power supply, 5V and/or 3.3V out.

The second one looks like a temperature sensor (thermistor) and the third one looks like an LED, like the red one on the board, only not red.

 

The third one could well be an infra-red LED.

Thanks. I think you're right. I connected it to 5V and GND with a voltmeter and the voltage changes when I wrap may hand around it.
