In this project, we will see the Automatic Room Lights using Arduino and PIR Sensor, where the lights in the room will automatically turn ON and OFF by detecting the presence of a human. Such ...

The circuit diagram of the automated washroom light is shown in Fig. 2. It is built around Arduino Uno ... insufficient to energize the relay. So, NPN transistor T1 (BC547) is used for amplification ...

This circuit can be used for automatic light control and 6V battery charging. It monitors the battery level and switches to charging and overcharging protection modes accordingly. The block diagram is ...

It’s like Dark and light Detector circuit but this time we are using Arduino to get more control over light. In this circuit, we are making a Light Sensor using LDR with Arduino to control a bulb/CFL ...

In this project we have studied the optimization of traffic light controller in a City using IR sensors and Arduino . Figure-4. shows the complete circuit diagram of Arduino board. By using this ...

The block control project now incorporates “all” solid-state components controlled by an Arduino microcontroller. I refer to this updated article as “CTC Signals 2.0.” The scope of the project ...
