Arduino Nano sends this information to the LoRa E5 mini board. It acts as the communication gateway, directly transmitting the heart-rate data to a chosen gateway. This setup enables continuous monitoring of the user
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 ci...
First of all we have configured the A4 pin of the arduino uno as input pin to read the the LDR sensor output. In the setup function, the “Serial.begin(9600)” command will help in communication between the Arduino and serial monitor. In the loop function, we will read from the sensor...
Copy the full code into the Arduino IDE, then upload it to your ESP8266 development board. Open the serial monitor, and you can see the ESP8266 board connecting to the Wi-Fi network and then to the MQTT broker. Using MQTTX to Send Messages to ESP8266 To test this functionality, you ...

In our case, Arduino can provide sufficient voltage to drive the motors but it cannot provide ample current. Arduino UNO’s 5v and GND pins have current rating of 200mA while any GPIO pin has rating of 40 mA. This is way lower than the starting and stall currents motors we need . ...
After uploading the Arduino Sketch to ESP32 Board, open the Serial Monitor Window and Monitor Serial data received from Modbus device. Testing & Troubleshooting Test with Modbus Simulator InstallQModMasteron a PC. Configure a virtual slave device: ...
We present an automation project based on Arduino to monitor and control the cinema hall indoor lighting based on the identification of designed sensor which detects the change in desired voltage. We aim to adopt different systems to achieve the required operations that no longer require time-...
// Serial monitor setup Serial.begin(115200); } void loop() { Serial.print("Hello"); digitalWrite(ledPin, HIGH); delay(500); Serial.println(" world!"); digitalWrite(ledPin, LOW); delay(500); } Aside from using GPIO pin 2 (instead of Arduino digital output pin 13) and adding the...
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.
