Another two-day workshop about microcontrollers, soldering and Tinusaur

Another two-day workshop about microcontrollers, soldering and Tinusaur

There was another “Microcontrollers, soldering and Tinusaurworkshop in our town of Veliko Tarnovo, few days ago..

The first day we assembled some boards, the second day we wrote some programs.

For the younger kids, there were much simpler things to do – soldering blinking LED with 2 transistors, few other components, and a battery.

Day 1

Just assembling various boards.

Tinusaur Board

This is the Tinusaur Board from the Tinusaur Starter 2 kit.

Tinusaur Board Parts

It wasn’t difficult for anyone to do that. There are markings on the PCB that tell you where to put each component and in what direction.

The only important thing to know is that you solder the RESET button last, before that you solder the batter socket on the bottom side of the PCB.

Tinusaur Shield LEDx2

This is the Shield LEDx2 from the Tinusaur Starter 2 kit.

This shield is an upgrade from the previous Tinusaur Starter where we had to solder the LED and the resistor to a tiny 2-pin male header. With the shield is so much easier and fun.

LED Matrix 8×8 with MAX7219 Controller

This is a LED matrix 8×8 with a MAX7219 controller.

LED Matrix 8x8 MAX7219 Controller

That was something new. They sell on eBay at very affordable price: http://www.ebay.com/itm/191736585164

Even while we’re soldering it people were coming with ideas what we could do with it.

Day 2

The second day was dedicated to programming what we’ve assembled the previous day.

Software and Arduino IDE Setup

That’s how we started the day 2.

Short guide about how to setup the Arduino IDE to work with the Tinusaur boards is available at Arduino IDE Setup page.

Blinking LED

The “Hello, World!” in the microcontrollers’ world.

Source code available at https://bitbucket.org/tinusaur/tutorials/src/default/tut004a_blinking_leds/.

Separate blog post and tutorial page will be available soon.

LED Matrix 8×8

The biggest challenge here was to make the MAX7219LED8x8 library to work in the Arduino IDE environment.

We’ll do another post about that in the next few days.

The First Tinusaur Workshop

The first official Tinusaur workshop took place last Sunday (on the 14th of December) in the Veliko Turnovo University “St. St. Cyril and Methodius”. It was really great!

The workshop was attended by 22 people of age 16 to 44.

The Tinusaur Workshop

As you may have guessed already it was for the absolute beginners so we first learned how to solder basic things like resistors, capacitors and other small parts. Then we move to soldering The Tinusair Board.

The second part was programming the with the “Hello World” of the microcontrollers – a blinking LED.

Not all people who wanted could attend the even so we may organize another one in the first months of the next year.
