Step 1: What You Will Need

Arduino UNO (or any other board)

APDS9960 proximity gesture sensor
L298N DC MOTOR CONTROLER Driver
OLED Display
Batteries
DC Motor
Breadboard
Jumper wires
Visuino program: Download Visuino

Step 2: The Circuit

Connect digital pin(2) from Arduino to motor driver pin (IN2)
Connect digital pin(3) from Arduino to motor driver pin (IN1)
Connect DC one motor to one side of motor driver
Connect Power supply (batteries) pin (gnd) to motor driver controler pin (gnd)
Connect Power supply (batteries) pin (+) to motor driver controler pin (+)
Connect GND from Arduino to motor driver controler pin (gnd)
Connect OLED Display pin (GND) to Arduino pin (GND)
Connect OLED Display pin (VCC) to Arduino pin (5V)
Connect OLED Display pin (SCL) to Arduino pin (SCL)
Connect OLED Display pin (SDA) to Arduino pin (SDA)
Connect Sensor Pin [GND] to Arduino board pin [GND]
Connect Sensor Pin [Vin] to Arduino board pin [3.3V]
Connect Sensor Pin [SDA] to Arduino board pin [SDA]
Connect Sensor Pin [SCL] to Arduino board pin [SCL]

Step 3: Start Visuino, and Select the Arduino UNO Board Type

The Visuino: https://www.visuino.eu needs to be installed. Start Visuino as shown in the first picture Click on the "Tools" button on the Arduino component (Picture 1) in Visuino When the dialog appears, select "Arduino UNO" as shown on Picture 2

Step 4: In Visuino Add Components

Add "Gesture Color Proximity APDS9960 I2C" component
Add "Up/Down Counter" component
Add "SR Flip-Flop" component
Add "Divide Analog By Value" component
Add "Speed and Direction To Speed" component
Add "Dual DC Motor Driver Digital and PWM Pins Bridge (L9110S, L298N)" component
Add "Text Value" component
Add "SSD1306/SH1106 OLED Display (I2C)" component
Add "Delay" component

Step 5: In Visuino Set Components

Select "UpDownCounter1" component and in the properties window set Max>value to 10
Select "UpDownCounter1" component and in the properties window set Min>value to 0
Select "DivideByValue1" component and in the properties window set value to 10
Select "SpeedAndDirectionToSpeed1" component and in the properties window set Initial Reverse to True, and Initial Speed to 1
Select "Delay1" component and in the properties window set Can Restart to False and Interval (uS) to 1000000
Double click on the "TextValue1" component and in the Elements window drag 4X "Set Value" to the left side
On the left side select "Set Value1" and in the properties window set Value to "FASTER"
On the left side select "Set Value2" and in the properties window set Value to "SLOWER"
On the left side select "Set Value3" and in the properties window set Value to "LEFT"
On the left side select "Set Value4" and in the properties window set Value to "RIGHT"
Close the Elements window
Double click on the "DisplayOLED1" component and in the Elements drag "Text Field" to the left and "Fill Screen" to the left
On the left side select "Text Field1" and in the properties window set size to 3
Close the Elements window

Step 6: In Visuino Connect Components

Connect "GestureColorProximity1" pin Gesture>Up to "UpDownCounter1" pin Up

Connect "GestureColorProximity1" pin Gesture>Up to "TextValue1>Set Value1" pin In

Connect "GestureColorProximity1" pin Gesture>Down to "UpDownCounter1" pin Down
Connect "GestureColorProximity1" pin Gesture>Down to "TextValue1>Set Value2" pin In
Connect "GestureColorProximity1" pin Gesture>Left to "SRFlipFlop1" pin Set
Connect "GestureColorProximity1" pin Gesture>Left to "TextValue1>Set Value3" pin In
Connect "GestureColorProximity1" pin Gesture>Right to "SRFlipFlop1" pin Reset
Connect "GestureColorProximity1" pin Gesture>Right to "TextValue1>Set Value4" pin In
Connect "GestureColorProximity1" pin Control I2C to Arduino board pin I2C In
Connect "UpDownCounter1" pin Out to "DivideByValue1" pin In
Connect "DivideByValue1" pin Out to "SpeedAndDirectionToSpeed1" pin speed
Connect "SRFlipFlop1" pin Out to "SpeedAndDirectionToSpeed1" pin Reverse
Connect "SpeedAndDirectionToSpeed1" pin Out to "DualMotorDriver1" Motors[0]>In
Connect "DualMotorDriver1" Motors[0] pin Direction(B) to Arduino board digital pin 2
Connect "DualMotorDriver1" Motors[0] pin Speed(A) to Arduino board digital pin 3
Connect "TextValue1" pin Out to "DisplayOLED1" > Text Field1>Clock
Connect "TextValue1" pin Out to "DisplayOLED1" > Text Field1>In
Connect "TextValue1" pin Out to "Delay1" pin Start
Connect "Delay1" pin Out to "DisplayOLED1" > Fill Screen1>Clock
Connect "DisplayOLED1" pin Out I2C to Arduino board pin I2C In

Step 7: Generate, Compile, and Upload the Arduino Code

In Visuino, at the bottom click on the "Build" Tab, make sure the correct port is selected, then click on the "Compile/Build and Upload" button.

Step 8: Play

If you power the Arduino UNO module, and make a gesture over the proximity gesture sensor the motor will start to move and the OLED Display will start to show the Direction, watch the video for the detail demonstration.
