Advanced Projects
Step up your game with IoT dashboards, sensor networks, and multi-component builds using ESP32, Arduino Mega, and more.
Smart Weather Station
Build a comprehensive WiFi-enabled weather station with the ESP32. Read temperature, humidity, and barometric pressure using the BME280 sensor and display it on a beautiful web dashboard.
Home Automation Hub
Take control of your room. Create an ESP32 web server that manages multiple relays to switch AC appliances safely, complete with a responsive HTML/CSS dashboard.
RFID Attendance System
Build a robust check-in system using the Arduino Mega. Scan RFID tags with the RC522, track timestamps using a DS3231 RTC, and log the data securely to a MicroSD card.
IoT Soil Moisture Monitor
Connect your plants to the internet. Use an ESP8266 and a capacitive soil sensor to view live moisture levels on a web dashboard.
Bluetooth RC Car
Build a smartphone-controlled rover using an Arduino, an HC-05 Bluetooth module, and an L298N motor driver.
Fingerprint Door Lock
Secure your room with biometrics. Wire an AS608 optical fingerprint scanner to an Arduino to actuate a servo locking mechanism.
Dual-Axis Solar Tracker
Maximize solar panel efficiency. Use 4 LDRs and 2 servos to actively track the suns position across the sky.
Pulse Oximeter
Measure human vitals. Use a MAX30102 sensor and an OLED display to show real-time heart rate and blood oxygen levels.
Voice-Controlled Appliances
Hey Google, turn on the lights. Use an ESP32 to emulate a smart home device compatible with Alexa and Google Assistant.
Touchless Smart Dustbin
Keep your hands clean. An ultrasonic sensor detects your hand and a servo automatically opens the lid of the trash can.
Live Crypto/Stocks Ticker
Fetch live market data from the internet via REST APIs and display it on a colorful TFT LCD using an ESP32.
Automated Watering System
Never forget to water your garden. Arduino reads multiple soil sensors and triggers water pumps via relays when dry.
Digital Measuring Wheel
Measure long distances by rolling a wheel. Use a rotary encoder to count steps and display the distance on a 16x2 LCD.
Li-Fi Data Transfer System
Wireless light-based communication. Transmit high-fidelity audio or digital data through modulated visible light using an LED transmitter and photodiode receiver.
IoT Patient Health Tracker
A wearable smart health system using ESP32 to monitor real-time heart rate, SpO2 levels, and skin temperature, hosting a localized web analytics dashboard.
RFID Smart Car Parking System
Automate vehicle entry and capacity logging. Scan authorized RFID cards to lift a servo gate, and track open parking bays via infrared sensors.
Air & Water Pollution Smartwatch
A wearable multi-sensor diagnostic device. Analyze air purity PPM indexes (MQ-135) and water quality TDS thresholds, rendered on a sleek smartwatch OLED UI.
Biometric Fingerprint Bank Locker
Construct a secure vault system. Validate authorized users via AS608 biometrics, driving a heavy-duty 12V solenoid lock with active sound alarm deterrents.
ESP32-CAM Security Camera
Stream live MJPEG video from anywhere on your network. The ESP32-CAM module serves a browser-viewable security feed and optionally records to a MicroSD card on motion.
Smart Energy Meter
Measure real-world mains voltage with a ZMPT101B and current with an ACS712 Hall sensor. Calculate true power, energy (kWh), and cost — display live on an LCD dashboard.
NRF24L01 Wireless Data Link
Build a cable-free 2-way sensor bridge using two NRF24L01 2.4 GHz radio modules. Transmit temperature, button states, or any data up to 100 m line-of-sight.
OLED Audio Spectrum Analyzer
Visualize sound in real time. Feed audio into a MSGEQ7 7-band equalizer IC, read the 7 frequency levels with Arduino, and render an animated bar graph on a 128×64 OLED.
GPS Location Tracker
Parse live NMEA sentences from a Neo-6M GPS module on an ESP32. Display latitude, longitude, speed, and altitude on an OLED — and serve a Google Maps embed via WiFi.
MQTT IoT Sensor Dashboard
Connect your ESP32 sensors to the cloud. Publish temperature, humidity, and motion events over MQTT to a Node-RED dashboard visible from anywhere in the world.
Smart Video Doorbell
Build a DIY Ring doorbell with an ESP32-CAM and a PIR sensor. Capture a photo when someone approaches, stream live video, and push a Telegram notification to your phone.
Arduino CNC Pen Plotter
Build a 2-axis drawing machine using NEMA 17 stepper motors and GRBL firmware. Send G-code from Inkscape or Universal Gcode Sender to plot vector images on paper.
