- (10138) Stockton STEM Badge completed
Press the button to start the lights! - (9958) Stockton STEM Badge battery
Note the orientation of the holder; reversing it will make it difficult to insert the battery later. - (9796) Stockton STEM Badge components
- (9776) Stockton STEM Badge LEDs
- (9774) Stockton STEM Badge battery
The battery holder is a simple metal cage that solders to the underside of the board. - (9694) Stockton STEM Badge LEDs
- (9647) 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. - (9595) Stockton STEM Badge IC
The IC pins need to be straight and line up with their receptacles in the socket. - (9534) Stockton STEM Badge battery
It is possible for the holder to become hot during soldering; be careful when handling immediately after soldering. - (9496) Stockton STEM Badge IC
When inserting the IC, firm but controlled pressure is needed to avoid bending the pins. - (9423) Stockton STEM Badge LEDs
The case of an LED can crack if the legs are bent too close to it; even after placing the LED on the board, only bend the legs slightly to hold it in place. - (9233) Stockton STEM Badge battery
The battery should sit snugly under the holder. - (9212) Stockton STEM Badge IC
Once pushed all the way in, the IC may sit above the socket, but it will be parallel to it. - (9168) Stockton STEM Badge LEDs
Notice how the LEDs typically have one leg longer than the other; this is called the "anode". The colored case also has one flat side, opposite the longer leg; the leg on this side is called the "cathode". Also, note the distinctive shape of what is inside the colored case; this can also be used to help determine its orientation. The gap at the top of the metal surface is always on the anode side. LEDs can only be used the right way round so determining orientation is important. - (9121) Stockton STEM Badge battery
Note the orientation of the battery. The "+" side contacts the battery holder.
