What do you need to build an Arduino Speed Sensor. Building an Arduino speed detector using IR technology to measure the speed of a moving object is much more cost-effective, and it is also very ...
Circuit Diagram for Sound Sensor Module. ... If you want to turn on or off your home appliances with sound then you can build yourself a simple whistle detecting circuit with Arduino and sound sensor.
SDP600 series sensors run on 3.3V!! not 5 Don't worry the cool thing about I2C is that as long as the lowest voltage of any connected device (in this case the sensor with 3.3v) is higher than the ...
I2C protocol makes it easier to connect more ICs using only 2 wires SDA and SCL and allows communication between them at relatively low speed. The I2C bus or TWI (Two Wire Interface) allows a single ...
Step 3: Making the Circuit. Now, as we know how the components work, let’s go ahead and assemble theses components together and make a circuit as shown below. The Ultrasonic sensor is powered by 5V ...
So in this article we will learn how to use any MQ series gas sensor with Arduino and showing the output in PPM (parts per million). PPM is also expressed as milligrams per litre (mg/L). These sensors ...
