Arduino Project 5: Digital audio player

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 Masterclass Part 4: Build a mini robot

Meet Rolly our first autonomous microbot based on an Arduino Uno microcontroller and our own ‘special sauce’ software. The Arduino Uno might be an aging 8-bit microcontroller board but when it comes to interacting with the outside world it’s much easier to use than an Intel Core or AMD FX CPU. The Uno’s cache of…

Arduino Masterclass Part 1: Make your own hardware

Arduino Masterclass Part 1: Make your own hardware

The world is going nuts over the Raspberry Pi single-board computer (SBC) for being a whole system under $50. In reality though the Pi isn’t actually the cheapest computing device available. If you want really cheap how does $13.50 sound for a mini computer that can plug into your PC’s USB port be programmed in…
