Components required

1 Smowboard Think Mini
1 Servo Motor
1 green LED
1 100 ohm resistor
1 push button
2 male-to-male jumper wires
5 male-to-female jumper wires

In this toll barrier circuit, a servo motor is employed as the central component to emulate the toll gate's movement. The servo motor's ground is connected to Smowboard, with power supplied from the Vin pin of the Smowboard. The motor is controlled by the Smowboard through a connection to pin number 2. Additionally, an LED is integrated to signal the driver when to proceed. The LED's cathode is grounded to the Smowboard with a 100-ohm resistor in series to limit current flow, and the anode is linked to pin number 4 of the Smowboard.

A push button, pivotal to the system's activation, is grounded by connecting one pin to the Smowboard's ground and the other to pin number 23. When the push button is clicked, the Smowboard intelligently manages the servo motor's rotation, causing it to turn by 90 degrees. Simultaneously, the Smowboard regulates the voltage across the LED, causing it to illuminate. This synchronized operation provides a clear visual cue to the driver, signaling them to proceed through the toll barrier.

The utilization of Smowcode not only facilitated a robust and precise servo motor control system but also enhanced the overall user experience. This project not only showcases the potential of Smowcode in creating interactive and responsive systems but also demonstrates its practical application in enhancing everyday processes for improved efficiency and user engagement.
