Problem statement: Develop the code in Arduino to interface an LM35 temperature sensor (Assume the sensor is connected to Arduino Analog pin A0) with an Arduino Uno and control the onboard LED based ...

The DS18B20 temperature sensor is a digital sensor that uses a 1-Wire interface to communicate with an Arduino board. The sensor is capable of measuring temperatures between -55 and 125 degrees ...

Arduino DHT22 Code for Interfacing the Sensor Module. Now let’s look at the code for interfacing the DHT22 sensor. For that first install the Adafruit’s DHT sensor library and Adafruit Unified Sensor ...

This isn’t about connecting a temperature sensor in your Arduino. ... or an artifact of the interrupts/code ... The temp sensor 3 pin devices are simple and cheap but good for 0.5 deg C ...

If your Arduino soil moisture sensor isn't working, check these common issues: verify all wire connections are secure, ensure you're using the correct Arduino pins (A0 for analog, digital pin for ...

We’d seen it done with buttons, switches, gestures, capacitive touch, and IR remote, but never like this. [electron_plumber] made an LED that can be blown out like a candle, and amazingly it … ...

You also need to select the transistor by the type of fan that you use. In my case I used the well-known BD139 transistor and a 9V battery to provide power to the fan and transistor. The LM35 ...

A thermistor can be used to compensate for temperature variation in other components of an electronic circuit. Here is an Arduino experiment with a famed linear active thermistor chip MCP9700A from ...
