LDR photo-resistor R10 sense ambient light and according of this level, adjust brightness of led segments. Temperature sensor DS18B20 is connected to pin IO5 of microprocessor U1. It is prepared to ...

As explained by Arduino to Go, each color band on the resistor corresponds to a number but this can differ depending on the band's placement. It's not complicated, but the sheer number of colors ...

Pranking your family and friends with a whoopee cushion and fake spider is fun and all, but if you're looking to add a touch of electronics to your next practical joke, check out this Arduino ...

Let’s begin by carefully cutting a perforated prototyping circuit board to the desired shape for your tiny line follower robot's chassis along with custom holes to hold the coreless motors and a ...

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 ...

Circuit connections Begin by connecting an LDR with a 10K resistor in a voltage-divider network. Join the LDR side of the network to the 5V DC and the resistor side of the network to ground (because ...

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 ...

Circuit and working Circuit diagram of an LED as a light sensor is shown in Fig. 1. It is built around op-amp CA3140 (IC1), transistors BC547 (T1) and BC337 (T2). Fig. 1: Circuit diagram of an LED as ...

To track the sun in two directions that is elevation and azimuth, a dual-axis tracking prototype is developed to capture the maximum sun rays by tracking the movement of the sun in four different ...
