these are my codes in java using the following impoted libraries from maven please fix the errors in my code. the errors are Pin buttonPin = new FirmataPin("D4"); Pin moistureSensorPin = new Pin(2); Pin waterPumpPin = new Pin(7); this blovk of code is still red. github.kurbatov.firmata4j io.github.java.native.jssc slf4j.jcl
