INTERACTIVE LED CIRCUIT

In this circuit demo, I only used 3 leds in my demo because I forgot to take away more leds. One problem I faced was that the yellow led did not light up after the potentiometer was rotated, then I considered that it might be a voltage problem, and modulated the power supply of the link board to 5v, and it was solved.

code：

<textarea>void setup() {

// put your setup code here, to run once: Serial.begin(9600); pinMode(9, OUTPUT); pinMode(10, OUTPUT); pinMode(11, OUTPUT); //pushbutton pinMode(13,INPUT); digitalWrite(13,HIGH); } void loop() { // put your main code here, to run repeatedly: if(digitalRead(13)==0){ //yellow digitalWrite(11,HIGH); digitalWrite(10,LOW); digitalWrite(9,LOW); delay(1000); //red digitalWrite(11,LOW); digitalWrite(10,HIGH); digitalWrite(9,LOW); delay(1000); //green digitalWrite(11,LOW); digitalWrite(10,LOW); digitalWrite(9,HIGH); delay(1000); } else{ if(analogRead(A1)<400){ digitalWrite(9,LOW); digitalWrite(10, LOW); digitalWrite(11, LOW); } if(analogRead(A1)>400&analogRead(A1)<600){ digitalWrite(9,LOW); digitalWrite(10, LOW); digitalWrite(11, LOW); } if(analogRead(A1)>600&analogRead(A1)<800){ digitalWrite(9,HIGH); digitalWrite(10, LOW); digitalWrite(11, LOW); } if(analogRead(A1)>800&analogRead(A1)<1000){ digitalWrite(9,LOW); digitalWrite(10, HIGH); digitalWrite(11, LOW); } if(analogRead(A1)>1000){ digitalWrite(9,LOW); digitalWrite(10, LOW); digitalWrite(11, HIGH); } } }</textarea>

My artwork idea is to make a battery model similar to the power display of a mobile phone. Red, yellow and green represent different power levels. The power can be changed through the potentiometer, and the button can display the effect of the battery being charged.
