If you take a look to the circuit scheme published in the Alphanumeric LCD with Shift Register on Arduino you can see that there is the pin number 9 that is NC (not connected). In the shift register ...

Data Pin: Connect the data pin to digital pin D2 on the Arduino. This pin reads the temperature and humidity data, which we then send to the Blynk app. 3.LDR Sensor (Light Dependent Resistor): The LDR ...

This project is an on-demand logger using an Arduino Nano-based controller. Like several similar SD serial loggers, the Arduino, used in this application is a popular choice for development and has ...

Programming Tip: Always disconnect the GPS module's TX wire from Arduino Pin 0 before uploading code. The continuous GPS data interferes with programming. Reconnect after successful upload. As ...

Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — either via Bluetooth or Wi-Fi.

This project demonstrates how to use the CAN bus to transmit sensor data between two Arduino modules. One module reads data from an ultrasonic sensor and an ADXL345 accelerometer and sends it over the ...

Learn how to build, collect, and analyze real-time data using a low-cost data acquisition device trainer and a machine learning model. This first article in a two-part hands-on tutorial will show you ...

Upon receiving the request, the Arduino should read the distance data from the Sharp sensor and send it back to the ESP32 (arduino_part.ino). The positive of the battery should be connected to the Vin ...
