- (12310) Stockton STEM Badge battery
Note the orientation of the holder; reversing it will make it difficult to insert the battery later. - (12119) Stockton STEM Badge battery
The battery holder is a simple metal cage that solders to the underside of the board. - (12101) Stockton STEM Badge battery
The battery is a typical CR2032 button cell. Notice which side the "+" is on. - (11905) Stockton STEM Badge IC
The IC pins need to be straight and line up with their receptacles in the socket. - (11890) Stockton STEM Badge IC and socket
The chip, an integrated circuit, or IC, must also be used the correct way round. Both the chip and its socket have a notch at one end to identify its orientation. - (11858) Stockton STEM Badge battery
It is possible for the holder to become hot during soldering; be careful when handling immediately after soldering. - (11769) Stockton STEM Badge IC
When inserting the IC, firm but controlled pressure is needed to avoid bending the pins. - (11728) Stockton STEM Badge resistors
These are 47 ohm resistors; they limit the current supplied to the orange, yellow and green LEDs. The blue LED does not require one. - (11720) Stockton STEM Badge battery
The battery should sit snugly under the holder. - (11645) Stockton STEM Badge battery
Note the orientation of the battery. The "+" side contacts the battery holder. - (11537) Stockton STEM Badge IC
Once pushed all the way in, the IC may sit above the socket, but it will be parallel to it. - (11455) Stockton STEM Badge LEDs
- (11424) Stockton STEM Badge LEDs
- (11407) Stockton STEM Badge LEDs
While all components can be destroyed with an excess of heat during soldering, LEDs are especially susceptible to this. - (11404) Stockton STEM Badge completed
