Brown for these 1K8 resistors

Flux is normally added to help the solder flow from where it is not supposed to be (the jumper) to the wick

The 5mm Red-Blue Auto Flash LED is a two-color

Applied current flowing through this copper conduction path generates a magnetic field which the Hall IC converts into a proportional voltage

Breadboard Power Supply Module 3.3V/5V Soldering Tool Brown for these 1K8 resistorsThis is a Breadboard Power Supply Module 3. 3V 5V with a multi purpose female USB connection and two independent power lines that may be tuned to a 5V or 3. 3V output voltage or turned off completely. The ON OFF switch on the module is used to turn it on and off. The Breadboard Power Supply Module 3. 3V 5V securely fits in a typical 400 or 800 tie points breadboard, and it also has reverse polarity protection. It accepts 6. 5V to 12V input and outputs
