Arduino Project 9: Stompy the robot (part 2)

Stompy is one of the simpler and more compact four-legged walking robots you can build which makes him a great low-cost learning tool for understanding a little of the vast world of robotics. In part 1 of this project we covered the major pieces – how to put together the chassis and how to assemble…

Arduino Project 8: Stompy the robot (part 1)

Stompy the walking robot. Isn’t he cute? Our first Arduino robot called Rolly in our February issue proved to be a popular project. Powered by an Arduino Uno board it was easy to put together and cost very little. In this project we upped the ante again with our first walking robot appropriately called Stompy.…

Arduino Project 7: Build a Retro Gamebox

Our Retro Gamebox is built into a see-through container. The games market may well dwarf the music and movie industries combined in global revenue and new-release games offer lighting effects and texture detail that make you forget you’re in a game and not a movie. But there’s always something that tugs us back to retro…

Arduino Project 6: Web-controlled music player

Our NetPlay project is built on a standard breadboard. In our previous Arduino masterclass we briefly introduced the Ethernet Shield an Arduino expansion board that adds Ethernet connectivity plus microSD card storage. We used that storage as the basis of a simple one-button digital audio player. It was functional but limited to 8-bit mono WAV…

Arduino Project 5: Digital audio player

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 -…

Arduino Project 4: Enhancing your mini robot

Rolly our first autonomous microbot now enhanced to do more. 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…
