Guides

Learn about electronics, microcontrollers, and building your projects.

• Arduino for Beginners: Understanding the Basics — A friendly introduction to Arduino, breadboards, components, and circuits — no prior experience needed.
• Your First Arduino Project: Making an LED Blink — Write your first Arduino sketch and make the built-in LED blink — no wiring required.
• Your First Real Circuit: LED + Resistor on a Breadboard — Wire an LED and resistor on a breadboard, learn Ohm's Law basics, and control your first external circuit.
• Build an Auto-Nightlight with Arduino — Use a photoresistor and voltage divider to build an automatic nightlight that responds to ambient light levels.
• Build a Temperature & Humidity Monitor with Arduino — Read temperature and humidity with a DHT11 sensor and display live readings on an I2C LCD screen.
• Build a Distance-Controlled Servo with Arduino — Measure distance with an ultrasonic sensor and control a servo motor that tracks your hand position in real time.
• Build a Wi-Fi Weather Station with ESP8266 — Connect an ESP8266 to Wi-Fi, fetch live weather data from an API, and display it on an OLED screen.
• Build a Motion-Activated Light with Raspberry Pi — Detect motion with a PIR sensor and control a relay using Python and GPIO on the Raspberry Pi.
• Play Melodies with Arduino and a Piezo Buzzer — Use a passive piezo buzzer and the tone() function to play notes, scales, and full melodies from your Arduino.
• Control an LED Strip from Your Phone with ESP8266 — Build a web-controlled NeoPixel LED strip with color picker, effects, and brightness slider — all served from the ESP8266.
• Build a Smart Plant Watering System with Raspberry Pi — Automate plant care with a soil moisture sensor, relay-controlled pump, cooldown logic, and CSV data logging.
