Turn loads on and off with your Arduino! Use 5V to control up to 100V. Add a motor, solenoid, or get creative! P channel or N Channel.

This is version 2.0 of the previously successful kickstarter project I launched last year. I have a ton of these PCB boards left over and it got me thinking. Why not find a P channel MOSFET with the same pinout and use it to control the direction of the motor also. I looked around and found the IRF5210. I ordered up a batch and tested them out. All thats left to do now is order a large quantity for the price break and assemble the rest of the boards.

We have designed the Arduino CNC Shield to use all the pins that GRBL implemented. We have also added a few extra pins to make things a little easier. GRBL is opensource software that runs on an Arduino Uno that takes G-Code commands via Serial and turns the commands into motor signals. Now compatible with Raspberry PI.

HamShield lets your Arduino talk to far away people and things using amateur radio bands (Coverage: 136-170MHz, 200-260MHz, 400-520MHz)

HamShield lets your Arduino talk to far away people and things using powerful amateur radio bands! Best of all, the hardware and software is open source!

With the power of Arduino, you can use the HamShield to build and invent amazing things in minutes!

This tutorial provides a guide on how to set up an Arduino to measure the capacitance of a capacitor. This can be useful if the capacitor is unlabeled or if it is self-built.

Capacitance is an object’s ability to store an electric charge. Reasonably, this object is referred to as a capacitor. A capacitor that stores this charge in an electric field between two conductive plates is known as a parallel plate capacitor.

MOVI is an offline speech recognizer and voice synthesizer that adds voice control functionality to any Arduino project

MOVI stands for My Own Voice Interface! It is the first standalone speech recognizer and voice synthesizer for Arduino with full English sentence capability:
Up to 200 customizable English sentences.
Speaker independent
Standalone, cloudless and private
Very easy to program

MOVI provides an alternative to buttons, remote controls, or cell phones by letting you use full-sentence voice commands for tasks such as turning devices on and off, entering alarm codes, and carrying on programmed conversations with projects.

MOVI is plug and play! Connect the shield to your Arduino Uno or compatible board, connect an optional speaker, and you’re ready to go.

Time displayed on large 1″ (26mm) 7 segment displays with secondary 4×20 LCD information display. The clock can be used stand alone or provides the following pulses to drive slave clocks 1 sec alternating, 30 sec, 1 min , 1 hour, 24 hr, 15 min chime of quarter hours, hourly chime of hours.

An Arduino 328 Microprocessor is used to decode and display time & date from the DCF77 “Atomic” Clock in Mainflingen near Frankfurt Germany.
The DCF77 signal is decoded using the fantastic new DCF77 library written by Udo Klein meaning the clock stays in sync and keeps perfect time even with a massive amount of noise on the received DCF77 signal. Udo Klein’s DCF77 library also continually “Auto Tunes” the quartz crystal so in the rare event the signal can’t be decoded the clock remains accurate within 1 sec over many days.

When we need precision and repeatability, a stepper motor is always the solution. With the way it is designed, a stepper can only move from one step to the next and fix in that position. A typical motor has 200 steps per revolution; if we tell the motor to go 100 steps in one direction, it will turn exactly 180 degrees. It gets interesting when we only tell it to go one step and it turns exactly 1.8 degrees.

Vacuum fluorescent displays look really kinda fancy and cool to me, I really love the blue-breen color. That’s why I decided to write this Instructable about a clock based on this technology. This is my first instructable here, showing you how I have designed built my clock and how you can build yourself exactly the same or a similar clock that utilizes the VFD display. I’m not a native speaker – just for you to know if you’re wondering why some sentences might make no sense at all.

This ESP8266-01 WiFi Shield is an alternative to the Very Cheap/Simple Wifi Shield for Arduino and other micros. The Very Cheap/Simple Wifi Shield for Arduino and other micros uses an Adafruit HUZZAH ESP8266 module and is the simplest to wire up. However if you already have an ESP8266 module, you can use these instructions to make a WiFi Shield using it.

This instructable uses the ESP8266-01 module, if you have one of the other ESP8266 bare modules, provided the module has GPIO0 and GPIO2 available, then you can use these instructions. If the module makes GPIO15 accessible YOU MUST connect it to GND via a resistor with a value between 3K3 and 10K.

The LiquidCrystal library allows you to control LCD displays that are compatible with the Hitachi HD44780 driver. There are many of them out there, and you can usually find them by the 16-pin interface.

In this tutorial you will learn how to use LCD 16×2 display (and 20×4) with Arduino uno.

You will also learn how to use lcd.begin(), lcd.print() and lcd.setCursor() functions
