Two Arduino Unos, jumper wires. Concept: Connect SDA (A4) to SDA and SCL (A5) to SCL. Program one Uno as the "Master" (sends requests) and the other as the "Slave" (sends sensor data back). This is how complex robots divide tasks (e.g., one Uno controlling arms, another controlling wheels). Learning Outcome: The Wire.h library and multi-processing logic.
Here’s a versatile text you can use for a blog post, course description, or makerspace intro about . projects with arduino uno
: The "Hello World" of Arduino. You can expand this by using a potentiometer to adjust brightness or a push button to toggle the light. Ultrasonic Distance Sensor Two Arduino Unos, jumper wires
Using a Light Dependent Resistor (LDR), you can program the Uno to automatically turn on an LED when the room goes dark. Intermediate Projects: Real-World Utility This is how complex robots divide tasks (e
