Introduction: The LAMP:bit is a bolt-on/clip-on board for the BBC micro:bit
replicating a street light. The PCB has been designed to have the same physical
features of a street light, with the addition of a phototransistor to detect
changes in light levels.
Lamp: The LAMP:bit has a white 10mm LED. The LED is driven from pin P0 of
the BBC micro:bit.
Detect: The LAMP:bit has a single phototransistor used to detect changes in
light levels. When the phototransistor is illuminated with light, it then conducts
and P1 is pulled towards 3V. When dark, the phototransistor does not conduct
and P1 is pulled down towards 0V with a resistor.

Connection: 4 x M3 countersunk screws allow
the user to bolt the LAMP:bit onto the BBC
micro:bit.
Crocodile clips can also be used between the
pads on the LAMP:bit and the matching pads
on the BBC micro:bit.
Stand: The bottom section of the LAMP:bit
PCB is designed to break off and then slot
together with the main PCB to form a stable
cross base.
Power: Power is supplied from the BBC micro:bit connections via the 3V and
0V (GND) pins.
