Refer to the schematic diagram for connecting LDRs, motors, and the motor driver to the Arduino board. Upload the Code. Open light_following_robot.ino in the Arduino IDE and upload it to your Arduino ...

Working of LDR controlled LED using Arduino. As per the circuit diagram, we have made a voltage divider circuit using LDR and 100k resistor. The voltage divider output is feed to the analog pin of the ...

5. Build your own Mars Rover Robot using Arduino: This cool looking Arduino Project presents the construction of an Arduino-based Mars rover, emphasizing design, components, and assembly.It highlights ...

The circuit of Arduino-based shadow alarm is shown in Fig. 1. It consists of an Arduino board, power supply, light-dependent resistor (LDR) sensor, buzzer, relay driver and a few other components.

After uploading the code to the Arduino Uno, move your hand up and down over the LDR, thus changing the light intensity falling on the LDR. If all goes well, you should hear cool space sounds from ...

That means if you have everything working, save your circuit, and close your browser you’ll have to recreate your Arduino code next time. Luckily, I tested this out before I lost any work.

Open the Arduino software and paste the Arduino code (the text in the box near the bottom of the post) into a new sketch. Click Sketch > Verify / Compile to make sure the code is properly in there.
