In this article, we will interface TSL25911Ambient Light Sensor Module with Arduino. This article discusses the working of the TSL25911 sensor module along with the circuit diagram and Arduino code ...

Generally in voltage comparator mode, voltage at one input is kept fixed using a Zener diode or a potential divider resistor chain. In the circuit, the voltage at pin 3 is set by VR1 so as to keep the ...

In this tutorial, we will use one such sensor BH1750 Light Sensor Module and interface it with Arduino and show the Lux value over 16x2 LCD.

Little Bird Electronics posted an article about using an analog voltage reference with Arduino. This is a tool available when using an analog-to-digital converter. By setting up either an internal ...

In a typical voltage sensing implementation, a resistive voltage divider is used to scale the DC-link voltage to suit the input range of the voltage sensor. A differential output voltage that is ...

Switched-Voltage-Divider A microcontroller can switch a voltage divider on and off by means of a suitable PNP transistor placed on the high-side of the circuit. If the voltage on the high side of the ...

From the looks of it, his hardware configuration is relatively simple. All it uses is a TSL261 Light-to-Voltage sensor connected to an Arduino with an Ethernet shield attached.

The ultrasonic sensor measures the distance to the water surface and outputs a voltage. The voltage is scaled using a voltage divider to match the Arduino’s input range. The Arduino calculates the ...
