--------------------------

Arduino boards can interface with a variety of sensors that utilize analog readings. These sensors output continuous voltage levels, which the Arduino can read using its built-in Analog-to-Digital Converter (ADC). Below is a list of common analog sensors that can be used with Arduino:


****Light Sensors****

- **Photoresistor (LDR)**: This sensor changes resistance based on light intensity, allowing it to measure ambient light levels.


****Temperature Sensors****

- **KY-013 Temperature Sensor**: An analog temperature sensor that uses an NTC thermistor to measure temperatures from -55°C to +155°C.

- **LM35 Temperature Sensor**: Outputs a voltage proportional to the temperature in Celsius.


****Motion and Proximity Sensors****

- **Ultrasonic Sensor**: While primarily digital, some models offer analog outputs for distance measurement.

- **PIR Motion Sensor**: Some versions can provide an analog signal indicating the level of detected motion.


****Sound Sensors****

- **Sound Sensor Module**: Detects sound levels and outputs an analog voltage corresponding to the sound intensity.


****Environmental Sensors****

- **Soil Moisture Sensor**: Measures the volumetric water content in soil by providing an analog voltage based on moisture levels.

- **Gas Sensors (e.g., MQ series)**: These sensors detect various gases (like alcohol, smoke, etc.) and output an analog voltage based on gas concentration.


****Position and Movement Sensors****

- **Potentiometer**: A variable resistor that outputs a voltage based on its position, commonly used for user input in projects.

- **Joystick Module**: Provides two analog outputs corresponding to the X and Y positions of the joystick.


****Other Sensors****

- **Vibration Sensor**: Detects vibrations and outputs an analog signal based on the intensity of the vibrations.

- **Flex/Bend Sensor**: Changes resistance based on bending, providing an analog output related to the degree of flexing.


These sensors typically connect to one of the Arduino's analog pins (A0 through A5 on most boards), allowing you to use the `analogRead(pin)` function in your sketches to obtain readings. The readings are then scaled from 0 to 1023, corresponding to a voltage range of 0V to 5V (or 0V to 3.3V for some boards) due to the 10-bit ADC used in Arduino[1][2][3].

SunTracker - working

2/11 got everything mounted Sketch written 021125_suntracker_copy_20250211151900 seems to be working except LRR reasd zero 2/12 added 10k resistors to each let Connect one leg of each LDR to the 5V pin on the Arduino. Connect the other leg of each LDR to an analog pin on the Arduino: Top-left LDR to A0 Top-right LDR to A1 Bottom-left LDR to A2 Bottom-right LDR to A3 Connect a 10kΩ resistor from each analog pin to the ground (GND) pin on the Ardui getting good readings from LDRs Need add battery for servos Added batt but readings erratic
