PM2.5/Air Quality Monitor Using ArduinoDust, known as "airborne particles", refers to solid particles that are suspended in air (diameter≤100μm). Among them, dust with diameter<2.5μm, known as "fine particulate matter", is referred t...
Well you can use any microcontroller, but I have used arduino due to its easy IDE. Basically function of arduino or any microcontroller here is to take voltage across 1 k ohm resistor as analog input and convert that value into mains a.c. voltage value by using a formula (explained in w...
Installing the Arduino IR Remote Library Now we will install the IR remote library. Simply go to Sketch->Include Library->Manage Library and search for Arduino IR Remote. Once it is done, go to examples and upload the IR demo sketch to the Arduino. Once it is done, start the serial mo...

11 is close-loop gain for this op-amp. Now, the amplified output voltage is sent to the Arduino, after that, the value of the primary winding current is received in the LCD screen. Arduino Code for AC Current Measurement The complete code is given at the end of this document. Here, ...
Here we describe how you can make your own PC based oscilloscope at a very low cost using a PC and an Arduino board as the hardware for signal acquisition.
In this project, design a healthcare solution over LoRa, using an Arduino Nano and a heart-rate sensor connected via the I2C bus.
After programming the ATmega328P IC, remove it from the Arduino Uno board. Assemble the circuit and use the programmed IC as shown in Fig. 3. Press F5 to run the VB application. Ensure the correct COM port is specified. Use the Arduino IDE’s serial monitor to verify commands and respon...
Fig. 1: Circuit diagram of DC panel meter using Arduino Power supply voltage is sampled using the voltage divider network built around resistors R1 and R2. Current consumed by the load is sampled using ACS712. Sampled voltage and current are given to Arduino, which is the brain of the circ...
Simply connect the Arduino Uno to VCC, RX, TX, and GND which are the four pins of a Bluetooth module to make it function. Since this Bluetooth module inside this project has a built-in voltage regulator, you may connect it directly to the Arduino’s 5V supply. Lastly, connect the RX ...
