Halloween Trick-or-Treat ESP32 tiny project

Summary

This project is designed to create an interactive Halloween trick-or-treat experience using PlatformIO. The project involves programming a microcontroller to control various Halloween-themed devices and sensors. Ready to be included in your halloween crafts!

Functionality

• Motion Detection: Detects motion through ultrasonic sensor to activate a servo motor. Attach it on your Halloween artifacts!
• Lighting Control: Enable two LED lights automatically due to motion detection to create a spooky atmosphere.
• Actuator: Allows the activation of a servo motor when a terrifying object is detected!

How to Build and Deploy

Prerequisites

• PlatformIO IDE installed
• Compatible microcontroller: ESP32 (developed on a ESP32 pico dev kit)
• Required sensors and actuators: HC-SR04 ultrasonic sensor, Micro servo 99, two red LEDs, two resistors, wires and a power source

Building and Deploying the Project

1. Install PlatformIO Core
2. Download development platform with examples
3. Extract ZIP archive
4. Run these commands:

git clone https://github.com/jfontecha/trick-or-treat-esp32.git
# Change directory to example

Ports and Connections

Below is a table detailing the ports and connections for the sensors and actuators to the ESP32 microcontroller:

Component	ESP32 Pin
Ultrasonic Sensor	GPIO 12 (trigger) 13 (echo)
Servo motor	GPIO 26
LED 1	GPIO 18
LED 2	GPIO 5

Ensure all connections are secure and double-check the pin assignments in your code.
