Vending Machine with Arduino UNO
Vending Machine with Arduino UNO The goal of this project is to make a controller for a vending machine based in Arduino UNO and using the sensors and the stuff contained in the given Arduino KIT: Components: The components and sensor used from the KIT in order to make this project are the following ones: Arduino UNO LCD Joystick DHT11 (Temperature/Humidity sensor) HC-SR504 (Ultrasonic Sensor) Button Red Led (LED1) Green Led (LED2) Resistors Male-to-male wires Connection: Now we detail the connection scheme for the project. This connection scheme was made using fritzing : NOTE: The joystick model used in fritzing has a different model, and the pins from left to right are: VCC-VRX-VRY-SW-GND, while the one used in the project (the one from the arduino KIT) is: GND-VCC-VRX-VRY-SW. Take this in consideration for the connection of your project. Code design. General concepts: In order to follow all the steps and specifications of the exercise, I decided to make the following things: I...
