Complete tutorial for building an advanced TCS34725 line-following robot with Arduino and PID control. Covers 3D chassis design, wiring, sensor calibration, PID tuning, and full code walkthrough. The natural upgrade from the beginner KY-033 line follower project.
Learn how to build a KY-033 line following robot with Arduino from scratch. This beginner tutorial covers 3D design, assembly, wiring, Arduino code, testing, tuning, and troubleshooting for a complete DIY line follower robot project.
Build OmObiArm, a DIY Bluetooth-controlled mobile robot arm powered by Arduino Mega, HC-05, Adafruit Motor Shield, and PCA9685 servo driver. Complete tutorial covering 3D design, assembly, wiring, Arduino code, MIT App Inventor app, calibration, troubleshooting, and FAQ.
Build an advanced autonomous robot car with Arduino Mega, four HC-SR04 ultrasonic sensors, HC-05 Bluetooth, and Adafruit Motor Shield. This step-by-step tutorial covers chassis assembly, wiring, Arduino code, an MIT App Inventor control app, and autonomous obstacle avoidance.
This tutorial walks through the HC-05 and HC-06 Bluetooth modules with Arduino. You’ll wire up the module, control an LED over Bluetooth, build a basic app in MIT App Inventor, and then take it further with relay-based lamp control. I also cover the common issues people run into and a few frequently asked questions.
Build a complete Arduino radar system using an HC-SR04 ultrasonic sensor and servo motor. This step-by-step tutorial covers wiring, Arduino code, optional buzzer alerts, and real-time Processing visualization. Includes troubleshooting, calibration tips, and FAQ.
