Learn how to create a circuit to increase the electrical current of the Arduino pins to activate loads that need more electrical current.

In this article, you will learn how to implement a feature to monitor the real-time clock battery and prevent problems in the circuit.

How to connect A6 GSM GPRS module with Arduino and also work with “AT” commands.

Work with AT Commands using your SIM800L module.

Easy to use interrupting thread handler. Does not relay on yield() or delay(ms) for switching and no pre-allocated stack needed.

Voltmeter can measure voltage up to 50VDC. It automatically calibrates when voltage of power supply is unstable.

Connect up to 10 buttons using a single interrupt.

Tester may block hardwired sensors of common burglary alarms and access systems so protected zone is open, even if the system's in arm mode.

RS-485/RS-422 shield, Arduino Uno and Modpoll (Linux).

Servo!!! The motor for Robots

Using a IR proximity sensor and microcontroller to find the local values of 'g' and will plot a real time damping curve.

PLC IEC-61131-3 ladder programming >>> Modbus TCP/IP >>> PID tuning >>> HMI >>> Wiring diagram.

Arduino and Python-based project that will help us read the sensor values and plot it on MATLAB.

How to display an image on an analog TV.

Receiving and sending the digital and analog signal through AD5669 interface with Arduino to detect the A/D pulses.

ATtiny85/45/25 are most inserting and useful boards, but can be difficult to code and use. So here is the development board!

The AD7793.h library provided by Analog Devices has been adapted for using on Arduino along with the SPI library.

A quick tutorial on how to interface the voice recognition module with few examples.

Achieve up to 60% saving on program memory space using Shox96 Guaranteed Text Compression Library for Arduino Uno and upwards.

Arduios is like a OS for the arduino, it enables you to use a sketch in different usecases, without having to upload a new one every time.

Serial communication between Thorlabs PM101 power meter and Arduino.

More complex microcontroller projects often require a menu-driven interface. This library for XOD can help autogenerate them from a diagram.

This project is a continuous variator of supplied power for power tools, lights or heating. Works universally for AC or DC power supplies.

In this project, we are taking the distance value from an ultrasonic sensor and scaling the dimension of an image accordingly.
