Digital, analog na PWM
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
- Tandukanya ibimenyetso by’ibihugu bibiri, ibipimo na duty cycle.
Mbere y’iri somo
Digital isoma LOW cyangwa HIGH hakurikijwe imipaka ya voltage. ADC ihindura voltage yapimwe ikaba umubare mu rugero rwa board. PWM ihinduranya digital kenshi; duty cycle ni igice cy’igihe imara kuri HIGH. 50% bivuga kimwe cya kabiri cy’igihe kuri HIGH, si voltage ihoraho y’igice. PWM ishobora guhindura uko LED igaragara yaka.
Utubuto tw’ijanisha ry’urumuri, ubushyuhe n’urwego rw’amazi ni inyinjiza zo kwiga gusa. Ntitwerekana sensor runaka, voltage, calibration ya ADC cyangwa driver y’igikoresho. Ifoto ya board ntitanga model ya sensor.
Microcontroller ikoresha firmware yo gukora umurimo wihariye. Mudasobwa kuri board imwe ishobora gutangiza Linux no gukoresha porogaramu. Ikimenyetso cy’ishuri na mudasobwa y’ishuri bifite ibikenewe bitandukanye; hitamo ukurikije umurimo, voltage na pine, si izina gusa.
Kwiga gusa: kubaka circuit, simulation ya board, kohereza firmware no guhuza ibikoresho ntibiraboneka hano.
