The schematic diagram for the Sound Sensor ... microcontroller is really simple. As we all know by now the sensor outputs an analog signal and it's really easy to process the signal. We can use the ...

All you need are a few basic parts ... In the below image, you can see the actual hardware setup developed by using our Arduino sensor circuit diagram as a reference. Here you can see that I am ...

The project also makes use of Arduino Nano as microcontroller (MCU ... But, as shown in the block diagram, there may be any number of sensor nodes. They would all be transmitting their values. It may ...

Motion sensor alarms are readily available in the market, but these are expensive. Here is a simple and inexpensive Arduino based motion sensor alarm with voice alert. It can be used for security ...

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 Arduino board. The two 4.7K pull-up resistors must be used when using I2C ...

As we know that not all cars come with parking sensors. If we want to install an external parking sensor, it costs a lot of money. But luckily we can make a low-cost parking sensor by using Arduino ..

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller ... Here is ...

This project demonstrates how to recognize hand gestures using flex sensors and Arduino. The flex sensors ... Arduino via a voltage divider circuit. Ensure all connections are secure and follow the ...

Different circuits use ... all the components and make a switching circuit. A touch sensor is a touch-sensitive module which has 3 input/output pins. Power up this module by connecting the Vcc pin and ...
