We can control the led indicator by sending a signal from one of the GPIO of Raspberry to pin Yellow, by default this signal will be received by the GPIO 17 But if we want to we can change the position of the jumper and assign other GPIO as input we will connect to the yellow pin.
Tunaweza kudhibiti kiashiria imesababisha kwa kutuma ishara kutoka kwa mmoja wa GPIO ya ya Rasiberi na Weka Njano, kwa chaguo-msingi ishara hii itakuwa kupokea na ya GPIO 17 Lakini kama tunataka sisi kubadilisha msimamo wa ya jumper na mpangie mmoja GPIO kama ingizo sisi utakuwa kuungana kwa pin njano.
