dont use 250K
use 10K
oh wtf its a temp sensor
or a light sensor
whats the variable resistor
no it isnt
not wired like that
and the light sensor is what i meant
not wired like that, it isnt doing anything
anyway
250k isnt enough base drive
(5 - 0.7) / 250e3 =
0.0000172
so 15uA
* 100 is only 1.5mA, to run the bjt linear, which you dont want to do
well pretend its 50 and use a safety factory of %1000
you need a buffer, darlington at least
