Here at Hackaday, we see microcontroller based projects in all states of completion. Sometimes it makes the most sense to design systems from the ground up, and other times when simplicity or a quick project completion is desired, pre-built system boards are a better choice. We have compiled a list of boards that we commonly see in your submitted projects, split up by price range and with a little detail for reference.
After reading our list, sound off in the comments or on this forum post, and we may include your board in a follow-up guide at a later date. We will also be giving away 10 Hackaday stickers to the most insightful, the most original, and most useful advice given on the forum, so if you haven’t registered yet, now would be a perfect time. Winners of the sticker giveaway will be selected from the forum thread, and the final decision for prizes will be judged by the wit and whim of the Hackaday writing team. More prize details to follow in the thread. Read on for our guide based on past project submissions.

So, you want to do some programming but don’t have the budget of a major corporation? This is just the thing for you because all of these development environments are free of charge! Many Integrated Development Environments are marketed towards companies who have money to pay for such expensive environments. Here are the Top 5 Integrated Development Environments that are most widely used and recognized. Some will be used when programming past and future tutorials. The following are listed in no particular order and all make an excellent development environment.
There are alot more IDE’s out there that were not mentioned but should have been. We have posed the question at Hack A Day Answers “What are your Top 5 IDE’s?” Give us some feedback and we will be back with a revised list from the comments you give us!

In this tutorial we are going to cover packaging one of our applications into an .apk file and getting it ready for the Android Market. After we have completed this tutorial you should be able to use the tools provided in the AndroidSDK to sign your application, put the application on your phone and install it or send it to the Android Market. These will be great assets to have if you decide to develop applications that you may want to charge for. This tutorial will also be a change from the normal ones because it will include little, if any, code.
In this tutorial we will be pivoting from our last tutorial on Graphical Elements to start focusing on databases in Android development. The android platform uses SQLite databases in its applications and is one of five data storage options in android development. We will only be focusing on SQLite development in android because it is key to the construction of a workable/functional program. After this tutorial you should be able to implement a SQLite database that you are then able to insert and select items from tables in the database.
For this project we will be creating a Random Quote generator that has you enter quotes or sayings in a textbox and press a button to insert them into the database. We will issue a confirmation toast that allows us to see if the data was entered into the database successfully and the textbox will be blank. If a second button is pressed, the database will be accessed and told to select a random quote from the database to show in a toast on the screen.
