ADC1_0 reported random value even no input
ADC1_0 reported random value even no input. #define Sensor_A0_PIN 36 pinMode(Sensor_A0_PIN, INPUT); // loop int sensor_A0_R = analogRead(Sensor_A)_PIN); display.drawString(0, 20, "Sensor A0: " + String(sensor_A0_R)); The output of sensor_A0_R send to OLED. I see random value such as: 768, 829, 822, ...
