- (10740) Stockton STEM Badge completed
Press the button to start the lights! - (10538) Stockton STEM Badge battery
Note the orientation of the holder; reversing it will make it difficult to insert the battery later. - (10362) Stockton STEM Badge battery
The battery holder is a simple metal cage that solders to the underside of the board. - (10332) Stockton STEM Badge LEDs
- (10265) Stockton STEM Badge LEDs
- (10185) 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. - (10139) Stockton STEM Badge components
- (10129) Stockton STEM Badge IC
The IC pins need to be straight and line up with their receptacles in the socket. - (10079) Stockton STEM Badge battery
It is possible for the holder to become hot during soldering; be careful when handling immediately after soldering. - (10046) Stockton STEM Badge IC
When inserting the IC, firm but controlled pressure is needed to avoid bending the pins. - (9973) 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. - (9892) Stockton STEM Badge battery
The battery should sit snugly under the holder. - (9826) Stockton STEM Badge battery
Note the orientation of the battery. The "+" side contacts the battery holder. - (9826) Stockton STEM Badge IC
Once pushed all the way in, the IC may sit above the socket, but it will be parallel to it. - (9744) 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.
