This DIY gas leakage detector is designed for educational and basic monitoring purposes. For critical safety applications, ...

By counting the pulses from the output of the sensor, we can easily calculate the water flow rate (in litre/hour – L/hr) using a suitable conversion formula. The Arduino Sketch (code) uses the ...

In our case Arduino is the master and 3 x TC74 sensors are the slaves. As you can see in the schematic all three TC74 sensors have their SDA and SCL pins connected in series to pin A4 and A5 on the ...

Adding a photoresistor (light sensor) and a thermistor (temperature ... and the other to ground through a 10kΩ resistor and to Arduino's analog pin A0. I did the same with the thermistor and ...

A flex sensor is a different category of sensor, where the resistance changes depending on the extent of the flex or "bend". Such changes can be read as electrical signals on the Arduino's input pin.

hacked it in with an Arduino. The video does a wonderful job going into the details, but essentially by using an oxygen sensor with finer resolution (wide-band) and then outputting the appropriate ...

First, we'll connect our traffic light sensor to a generic breakout shield we have installed on our Arduino UNO: breakout shields are shields containing banks of analog and digital pins ...

The basic idea behind Arduino is to plug one or more small electronic sensors into the board's analog or digital connection pins, usually labeled on the front of the board next to the pin headers.

He suspected EMF interference so as a quick first step he decided to throw together an EMF detector using an Arduino. It uses a bank of LEDs as an indicator bar to reflect the EMF picked up by the ...
