- (14208) 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. - (13889) Stockton STEM Badge completed
Press the button to start the lights! - (13520) Stockton STEM Badge battery
Note the orientation of the holder; reversing it will make it difficult to insert the battery later. - (13407) 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. - (13311) Stockton STEM Badge battery
The battery holder is a simple metal cage that solders to the underside of the board. - (13295) Stockton STEM Badge battery
The battery is a typical CR2032 button cell. Notice which side the "+" is on. - (13224) Stockton STEM Badge battery
The battery should sit snugly under the holder. - (13179) Stockton STEM Badge resistor legs
The legs are then carefully bent to about 45 degrees to hold the resistor in place for soldering. - (13140) Stockton STEM Badge LEDs
The footprint for the LEDs also shows a flat edge; orientation of the LEDs needs to match that of the board. - (13112) Stockton STEM Badge IC
The IC pins need to be straight and line up with their receptacles in the socket. - (13088) Stockton STEM Badge battery
It is possible for the holder to become hot during soldering; be careful when handling immediately after soldering. - (12974) Stockton STEM Badge IC
When inserting the IC, firm but controlled pressure is needed to avoid bending the pins. - (12922) Stockton STEM Badge battery
Note the orientation of the battery. The "+" side contacts the battery holder. - (12885) 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. - (12827) Stockton STEM Badge LEDs
