Tutorial: Programming the HC-05 - AT mode - with Arduino

Tutorial: Programming the HC-05 AT commands - done easily with Arduino

What This Tutorial Covers

In this tutorial I will show you how to wire the HC-05 to Arduino UNO and get into the AT mode all done with CODE. This way there is no need for pulling pins high and low by hand and it is quick and convenient and easy. Also, I will go through the process of changing the bound rate, the name and demonstrate a few other useful AT commands. 

*Please note that this tutorial is for the HC-05.

Tuorial: Attiny84 / 85 and Bluetooth

What This Tutorial Covers

This tutorial is an expansion / continuation of the previous Bluetooth tutorial. In other words I will assume you are familiar with arduino and simple Bluetooth concepts. Also, I assume you know how to program an Attiny via arduino as an ISP or via a standalone programmer. I'm not going to be going over the code in detail unless it is something I didn't cover in the previous tutorial.

In this tutorial we will learn how to connect a Bluetooth module to an Attiny and how to make them talk! Exciting isint it? This will allow you to control a shrinkified arduino project wirelessly via Bluetooth from another arduino bluetooth enabled device, via a computer or even via a phone. In this tutorial I will cover how to control your Bluetooth enabled Attiny via a computer, but soon I will be doing a tutorial on how to accomplish this via an iPhone.

Little plans for the future work - Quadcopter!

Micro Micro QuadCopter

I have many plans in my head for the future projects and not enough time or money to make them all! But, here is one that could be very interesting for the future work... A QuadCopter! Not just any quadcopter, a micro quadcopter. 

Parts (detailed)

note: "~" = approximately
- attiny 84 (1 gram) ($3)
- IMU Analog Combo Board Razor - 6DOF Ultra-Thin IMU (estimating it to be < 6-7 grams) ($15)
- plantraco 7mm motors (4) @ (3.3 grams each w/ props*) ($20 for all)
- plantraco 4 channel receiver (1 gram) ($60)
- plantraco LP200-FR Bahoma Cell (small lipo = short flight might use bigger) @ (5.5 grams) ($15)
- frame + wireing (~10 gram) (~$20)

total weight should be ~38 grams and the price would be approximately $133 + shipping. Not bad huh?
All the tutorials and do it yourself for the quadcopters are about much bigger and thus more expensive models. Going micro does have a lot of drawbacks though. This will never lift a camera like I would like it to. It will never be as stable and it will be much harder to get it right! But that just adds to the fun. Also it would be the smallest and lightest quadcopter out there as far as I'm concerned.

Bluetooth + Arduino Tutorial

Bluetooth and its wonders. Set it up with Arduino and Attiny85!

Introduction

This is my very first tutorial and it is on Bluetooth with Arduino.  I feel this is necessary for the community as there are not so many of them out there. The ones that are floating around the web are highly outdated or just not to my taste. Sorry! I know I'm not the best one to do a tutorial either but I will try my best. I learned how to use the Seeeduino Bluetooth, or any Bluetooth the hard way. This is created to make it easier for you! 

note: When I was learning about how to add Bluetooth to my project I was following closely the Wiki page of Seeeduino Bluetooth Shield. Find it here. Also, I will be covering how to set up your Bluetooth as a slave. If you would like to learn how to set it up as a Master reference the link above.

I hope you enjoy this tutorial / how to
