Hello. I am trying to make this repeat so that it constantly reads the voltage and updates so that writedigitalpin will start or stop automatically. How can I do this?

if readVoltage(a,'A1') >= 2
    writeDigitalPin(a,'D2',1); 
elseif readVoltage(a,'A1') < 2 
     writeDigitalPin(a,'D2',0);
end

在 MATLAB Online 中打开

current_state = 0;
writeDigitalPin(a,'D2',current_state);
while true
    if readVoltage(a, 'A1') >= 2
        if current_state == 0; writeDigitalPin(a,'D2',1); end
        current_state = 1;
    else
        if current_state == 1; writeDigitalPin(a,'D2',0); end
        current_state = 0;
    end
end
