8 lines of code to setup and 1 line of code per variable for the Arduino, no programming on the PC side. USB-WiFi-Ethernet-Serial.

An example sketch that will read a simple toggle switch reliably, irrespective of the circuit design.

Sketch of transistor tester project from Karl-Heinz Kübbeler, so it's much simpler to study, modify, verify and upload to an Arduino.

With modern I2C Protocol for the LCD, minimizing the wiring. A Basic Version with the Arduino UNO and a feature rich Version with the MEGA.

A general tutorial on installing Arduino bootloader on ATmega8 AVR microcontroller and programming it using Arduino IDE.

Extension to Ben Eater's breadboard computer that allows saving/loading programs and works as a monitor, assembler and disassembler.

When it sees you, it won't stop following!

Get not only 5 volts but also 9, 12 volts (18 Watts max) out of any QC-compatible charger/power bank for supplying power hungry projects.

Connect up to 10 buttons using a single interrupt.

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

In this tutorial I will explain how to use the TIMER0 of Arduino

This Arduino-powered Web Oscilloscope supports trigger, and changing voltage/div, offset and time / div. It supports 6 channels.

A programmable, portable, rechargeable power supply based on Arduino featuring an OLED display for viewing V.I.P. of projects/prototypes.

A voltage to frequency converter can realize an opto-isolated analog input for Arduino or other microcontroller systems.

You need to send a command to Arduino.

This library creates an 8-bit IO port for Arduino by combining any 8 Arduino pins. With this library, one can send/get direct 8-bit data.

Equipped with a keyboard, Ethernet Shield and LCD monitor, is able to execute built-in command and even to send command to a telnet server!

Thermistor as thermometer.

Create a digital watch for Arduino combined with a 16x2 LCD Keypad Shield and using YAKINDU Statechart Tools.

A sensor that recognizes the name of the color of an object based on light sensing and a neural network that learned from previous examples.

This project uses an ultrasonic distance sensor to create a pocket of wave interference where a small object can be levitated.

Power management for portable Arduino projects.

This post will take you through a step by step instruction on how to use the Rakwireless RAK811 lora module with Arduino
