Amashanyarazi, ibimenyetso n’inzira ya LED
Ibirimo n’ubuhinduzi bwa en/rw/fr ni inyandiko z’agateganyo zitegereje abarimu bazi indimi.
Ifoto yo kumenya igikoresho gusa; si ikarita ya pine cyangwa insinga. Reba inkomoko y’ifoto.
Intego zo kwiga
- Kurikirana inzira ifunze kandi utandukanye GPIO, isoko na GND.
Mbere y’iri somo
Pine y’isoko itanga voltage yagenwe; GND ni aho bapimira n’inzira igarura amashanyarazi. GPIO ni pine yo kwakira cyangwa gutanga ikimenyetso, si isoko ry’amashanyarazi. Imipaka ya voltage n’umuriro iterwa na board. Ntugahuza ikimenyetso cya 5 V n’inyinjiza yemera 3.3 V gusa.
Mu rugero rwa LED yaka kuri HIGH, kurikira GPIO → rezisitori iri mu ruhererekane → anode (+) → cathode (−) → GND. Iyo inzira igaruka ibuze, inzira iba ifunguye. Rezisitori igabanya umuriro kandi ishobora kuba ku ruhande urwo ari rwo rwose rwa LED mu ruhererekane. Agaciro kayo gaterwa na voltage n’umuriro byemewe. Ntugahuze LED ku isoko nta rezisitori. LED nshya akenshi ifite ukuguru kurekure kwa anode n’uruhande rubase rwa cathode; iyo amaguru yaciwe reba datasheet.
Kwiga gusa: kubaka circuit, simulation ya board, kohereza firmware no guhuza ibikoresho ntibiraboneka hano.
