Aim
To create a candy dispenser that reacts to hand proximity.
Problem statement
The dispenser should include features such as a touchscreen or button interface for choosing candies, a dispensing mechanism, and the ability to accept payment or dispense candies for free. Additionally, consider incorporating features like customizable portion sizes, tracking inventory, and providing feedback on user preferences.
Material used
Input: IR Proximity Sensor
Brain: TinkerSpace Brain Board
Output: Servo Motor
Battery: 5V Lithium-ion rechargeable battery
Component description
IR Proximity sensor
The function of Ultrasonic Sensor is to detect hand
Servo Motor
Servo motor is used to dispense the candies when someone approaches.
TinkerSpace Brain Board
TinkerSpace board acts as brain of this project, its function is to monitor IR Proximity Sensor and Servo motor
Battery
5V Lithium-Ion battery is used to power-up this project
Working description
Case 1: When the person is detected, IR Proximity sensor turns ON and sends the signal to the Tinkerspace Brain Board. The brain board oscilates the servo motor to 90Degree
Case 2: When no person is detected, IR Proximity sensor turns ON and sends the signal to the Tinkerspace Brain Board. The brain board oscilates the servo motor to 0 Degree
Circuit Design (DesignSpace)
Step 1: Connect IR PROXIMITY to input 1
Step 2: Connect SERVO MOTOR to output 1
Step 3: Connect supply and test project.
