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 ...

Light and dark detection using an LDR. For this project, let’s stick to the LDR sensor module so we can select the light or dark detection by placing jumpers. We’ll be using this module to detect ...

Arduino Uno: The microcontroller board used for processing sensor data and controlling the robot.; LDRs (Light Dependent Resistors): Sensors used to detect the light intensity. Motor Driver Module: ...

The circuit of light detector is very simple and easy to build with very few components. As you can see in the LDR circuit diagram, it can be a distinguished as two smaller circuits; a) Voltage ...

Step 4: Assembling The Circuit. We will need to design two circuits for this project. The first circuit will be placed at a suitable place in a blind man’s stick and the second one will be an RF ...

Circuit and working of Optical Theremin Musical Instrument. Arduino-based theremin wired on a breadboard is shown in Fig. 2. The components required are Arduino Uno, buzzer, 1-kilo-ohm resistor, light ...

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.

Connect the circuit as shown in the circuit diagram. Press the button B1. Adjust the light in such a way that it falls on LDR. Now you can observe that if the torch is away from LDR, the light does ...
