For this, we need a light sensor to detect the light condition and some circuitry to control the Light sensor. It’s like Dark and light Detector circuit but this time we are using Arduino to get more ...

As shown in the block diagram, the Arduino microcontroller constantly monitors the values from the ultrasonic sensor which is placed outside the dustbin. When a person comes near the dustbin the ...

Fig. 2: Circuit diagram of a wireless sensor node. As shown in circuit diagram of a sensor node in Fig. 2, there are only five major components in the transmitter circuit: 1. Sensor DHT11 that has ...

The Arduino Uno Light Sensors detect ambient light levels. They typically use photodiodes or photoresistors to measure changes in light intensity. Commonly employed in automatic lighting systems, ...

Light sensor Dark sensor. 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 ...

Presented here is a humidity and temperature monitoring using Arduino. In this article, humidity and temperature information from DHT-11 sensor is analysed graphically on ThingSpeak platform using ...

How to integrate block control into your layout using an Arduino microcontroller The following project is an update of Gary D. Patterson’s “Simplified CTC signals” in the July 1988 issue of MR.
