So far in this series we’ve had a diverse look at how Arduino can interact with a range of real-world devices from servo motors to ultrasonic range finders TVs to humidity sensors. Now we’ll see if we could get the Arduino to make a few sounds. We’ll actually do a bit better than that – […]

Create an inexpensive basic wireless mesh network with arduinos and long range APC220 radio modules. Wireless mesh networks have the ability to accommodate non-functioning individual nodes and are resilient in challenging environments like forests and hills, where direct data transmission between points may be limited. Step 1: How the mesh works This is a wireless […]

You’ll need these: HC-SR04 – Get this ultrasonic sensor from eBay.com.au for $2. SG90 Servo Motor – We’ve seen this servo selling for around $4 on ebay. Motor drive shield – You can get this expansion board for $5 online. If you’re new to APC we’ve been spending the last few months of this Masterclass […]

If you ever wanted to integrate touch sensitivity into your project, this board could just do the trick. It’s a capacitive touch sensor. These sensors are used in our everyday consumer electronics like notebook trackpads, video game consoles, touchscreens…just to name a few. They work on the principle of alteration of the electrostatic field. The […]

Introduction EasyEDA is a free web-based electronic circuit design tool. It’s one stop design shop for your electronics projects, which offers schematic capture, spice simulation, PCB design and PCB order service. EasyEDA is designed to give electrical engineers, educators, engineering students and electronics hobbyists an Easier EDA Experience. More introduction about EasyEDA, you could check […]

In this guide I will explain how to use a Windows 8.1 phone, Arduino Uno board, and HC-05 Bluetooth module to build a wireless oscilloscope. The phone application has the critical functions of an oscilloscope, although the bandwidth is a measly 300 Hz. Still, if you want to see squiggly lines on your phone, it […]

This Lazy Old Geek (L.O.G.) loves Arduinos. I have noticed that a lot of sensors, like GPS, LCDs, magnetometers are 3.3Vdc sensors. But the standard Arduinos, Uno, RBBB are 5Vdc modules. So I decided I’m going to make more of my Arduino projects with 3.3Vdc AtMega328s. Now I’ve done this before but will go through […]

Do you have a habit of leaving notes on the fridge, now take it digital and add an Arduino to it. In this instructable I’m going to show you how to do just that. All you need is an Arduino, an LCD screen and a Bluetooth module to make this and a Android mobile to […]

his is a preliminary instructable that will take you through the steps I took to get the SR04 ULTRASONIC SENSOR  connected  and working to the Arduino. It will then be incorporated to my mini environment monitor.  Eventually, if it all fits, it will end up in a Startrek  toy tricorder casing I found in my […]

The purpose of this project is to design and build a simple light-following robot using an Arduino Duemilanove microcontroller board. I really wanted to share a robot project that was cheap, simple to build, and had a complete set of instructions for all of the different steps. I hope I’ve succeeded and I’d love to […]
