Automatic Street Light
An LDR senses dusk and a MOSFET switches a 12V LED lamp on, then off again at sunrise, with no flicker.
Animatronic Robot Eyes (EYE-2)
Two robot eyes that look around, blink, wink, get angry or sleepy, and follow your face with a camera.
Smart Medicine Dispenser
A 3D-printed 21-slot wheel drops each dose on time, an IR sensor sees it taken, and the family is alerted if it isn't.
Smart Bathroom Light
Motion lights switch off while you shower. This one uses motion AND a door sensor, so it stays on until the door opens again.
Solar Garden Motion Light
The sun charges a battery by day. At dusk it glows softly, and when someone walks in it goes to full brightness for 60 seconds.
Smart Plant Watering
A soil sensor reads moisture and a small pump waters the plant through a 3D-printed drip ring, even while you're away.
Tea-Serving Robot
Pick a desk on your phone. The robot follows a black tape line and stops at that desk with your tea.
Colour-Sorting Robot Arm
A colour sensor reads each block and a 3D-printed arm drops it in the matching bin.
Gesture-Controlled Robot Arm
Wear a glove with a tilt sensor. The arm copies your hand, with no wires and no app.
2-Axis Solar Sun Tracker
Four light sensors and two servos keep the panel facing the sun all day, for about 35% more energy in our simulation.
Gas Leak Auto-Shutoff
An MQ-6 sensor smells LPG. Within a second a servo turns the stove knob off, a fan starts and an alarm sounds.
Auto Curtain Opener
When morning light stays bright, a stepper motor pulls the curtain cord open.
Touchless Tap Saver
Water runs only while your hands are under the tap, so no tap is left running.
Photo Doorbell
When someone presses the bell, the ESP32-CAM sends their photo to your phone on Telegram.
Scheduled Pet Feeder
A clock module triggers meal times and a 3D-printed auger pushes out the same portion every time.
Cooker Whistle Counter
A sound sensor counts pressure-cooker whistles and, after the 3rd, a servo turns the gas knob off.
LPG Gas Level Meter
A load cell weighs the cylinder and your phone shows how much gas is left, with an alert at 20%.
Milk Boil-Over Guard
Two steel probe rods sit above the milk. When the foam touches them, the Arduino beeps and a servo lowers the flame.
Water Tank Level on Phone
An ultrasonic sensor on the tank lid measures the water level and your phone shows it live, with an overflow alert.
AC Bill Meter
A current sensor measures what your AC draws and the ESP32 shows the cost in rupees per day and per month.
Bike Side-Stand Alert
Start the bike with the side stand down and the buzzer warns you until you lift it.
Child-in-Car Alarm
If the car is locked and a motion sensor sees movement inside, the horn sounds and your phone gets an alert.
Smart Medicine Box
At dose time the box beeps. A lid sensor confirms it was opened and the family gets a message.
Terrace Rain Alert
A rain sensor on the terrace catches the first drops and your phone beeps, so the clothes come in dry.
