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 – […]
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 […]
PID Thermostat This is a PID thermostat for the arduino. It supports independent tuning parameters for multiple hardware ‘profiles’, and includes an autotune mode to estimate the PID parameters for a given setpoint. Installation Hardware DS18-series (I’m using the DS18B20) temperature sensor Solid-state relay rated for your power source 16×2 LCD display (I’m using the […]
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 […]
Build a low cost simple wireless mesh using arduinos and long range APC220 radio modules. Wireless mesh networks can handle individual nodes not working and are tolerant to environments such as forests and hills where data may not be able to go directly from one point to another. Step 1: How the mesh works This […]
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 […]
OK, this is not a fully autonomous “get you a beer, open it for you and then tweet about it” robodog (yet 😉 but if you’re itching to get past the blinky lights on a breadboard stage with your Arduino and you’re ten or know somebody that’s ten this might appeal to you. This is […]
