Building a standalone Arduino from scratch and programming it with ICSP

We thought this might be a good topic for the site as it’s something we have done recently, this article will explain how to set up your standalone Arduino project on a breadboard. This will also include uploading your program code via the ICSP connections. This isn’t technically “an Arduino” as we will be not including some components, such as a USB connection, reset switch or any on-board LEDs.

The end result will be a breadboard and your Arduino project running on it, without an actual Arduino board.

Getting Started with CPLDs – Part 4

cpldjIn this guide, we’re going to build up from the previous guide and add a button to our LED. Hopefully by now you’ve had a play with the Quartus II software and had a look through some of the logic elements in the library so I wont be explaining everything in minute detail. You should have a much better idea of what you’re doing now.

You’re going to need your CPLD board & programmer, a breadboard, LED, push button, 10K resistor, 220ohm resistor and some jumper wires.

Building a breakout board for a TI TMP708

TMP708Steve recently ordered several Texas Instruments TMP708 temperature switches. What he failed to realise however, is that the chips come in an SOT package which is tiny. After laughing at him for quite a while, I offered to build him a breakout board for the chips.

Here are the steps I took to make this tiny package useful for prototyping purposes. It’s by no means pretty but it will allow us to use the temperature switch on a breadboard.

How to give your Arduino robot eyes!… (Ultrasonic’s really!)

HCSR04_CloseupWhat robotics project doesn’t need eyes? By eyes we’re referring to HC-SR04 Ultrasonic Sensors. We have put together a quick and easy library to get started with using these sensors.

The HC-SR04 is a low cost, easy to use sensor that will measure distance by bouncing ultrasonic sound waves off of obstacles in front of it. Ideal applications for the HC-SR04 is using them for obstacle avoidance systems in your robots/RC cars – This will be quite short post as there isn’t much to it.
