Alguém poderia me auxiliar com o código abaixo: Quero usa-lo com modulo L293d, duvida onde ligar
Display Lcd Oled Modulo Para Arduino 0.96 I2c Iic Spi e o Encoder Decoder KY-040 Rotacional.

Outra duvida, muda alguma coisa no código

Em anexo circuito e o código.

I2c liga na saída i2c, spi na spi. Mas antes

-faça um led piscar (x).

Depois, só depois faça uma coisa por vez:

-faça girar o motor ( )

-controle sua velocidade por pwm ( )

-faça mover o servo pra lá e pra cá ( )

-escreva/desenhe algo no display. ( )

-leia algo do rotary encoder e mostre no display ( )

Imprima o texto acima e marque com x cada etapa vencida 😁
