7-Segments 2.3-inch Clock based on ESP32 D1 mini and time receiving from NTP. The Article describes drivers and power voltage circuit for required voltage value. On the display there is shown Time and ...

It's important to have a grasp of how to read Arduino resistors, as they're useful for controlling the current in an electrical circuit.

If you are just learning how to do Arduino projects or want to start, here are six fun and easy projects you can try that are perfect for beginner programmers.

This guide teaches you how to make a zippy little line-following robot. No microcontroller nor any programming is needed, only basic electronics!

Fig. 1: Wiring diagram for the LED desk lamp Working Regulated 5V DC from the Arduino Uno’s onboard linear voltage regulator powers the HC-05 compatible Bluetooth module. The module communicates with ...

To use a dark sensor instead, connect LM358 ‘s pin 7 of to one of Arduino’s digital I/O pins. As a dark sensor, the circuit will output as HIGH when it’s dark and a LOW when there’s light. The output ...

Learn here to interface RGB LED with Arduino. Circuit Diagram: The complete circuit diagram of this project is given above. The +5V and ground connection shown in the circuit diagram can be obtained ...

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 ...

Usually light dependent resistors (LDR) and photodiodes are used as light sensors to activate or deactivate circuits based on the presence or absence of light. But a common transparent LED can also be ...

This new approach will make use of the Light Depending Resistor (LDR) which is important to detect the sun light by following the source of the sun light location. AutoCAD software is being used to ...
