This blog is telling about my yesterday (19.3.2014) and how it went. I woke up 6.30 am as usual on workdays. Then I dressed and went to eat my normal nourishing breakfast, porridge and a cup of coffee. After finishing my breakfast I washed my teeth, watched tv a few moments, and then left to bus stop by walking. On the way to bus stop I saw and heard many different birds singing and flying around. Bus came on time and was on time at Lapua also. My actual schoolday started with subject called embedded systems at 8 am. There we continued to build and test the Arduino examples. I started to continue from example 10. By that example you can control an electric motor with two pushbuttons. First pushbutton starts and stops the motor and the other one changes direction of the motor. The motor gets operating voltage from 9V battery, because USB port´s voltage (5V) isn´t enought to run the motor. When that example was ready, working and checked by the teacher I continued to next example which was this time example 12, because example 11 was done earlier. Example 12 is about lighting a led with exploiting capacitance. What comes to components it was one of the simplest examples of the Starter kit. One led, two resistors and a couple of jump wires, that´s all. The led light´s when you hold from the jump wire. That´s about the capacitance. Capacitance is the ability of a body to store an electrical charge. Any object that can be electrically charged exhibits capacitance. Example 12 got also accepted by the teacher. After that the morning lessons were almost over and the first coffeebreak was approaching.

Coffeebreak started 9.30 am, as usual. On the time of the coffeebreak we went to Halpa-halli. That´s another usual thing we do on that time a day. After the coffeebreak our schoolday continued with English studies. English started at 10 am. There we learned how to write a CV in English and what you should notice when you write it. We also listened and translated a text chapter into Finnish and did some exercises related to it. In conclution we dealt a exam to next week´s wednesday. The English lessons ended to lunchbreak at 11.30 am. Normally lunchbreak starts at 11 am, but we have decided to complete two lessons at once and start the lunchbreak then.

After the lunchbreak we continued with embedded systems again. The teacher showed how dimmered led looks in oscillosscope and told us how you dimmer led in practise. After that we measured blinking led´s pulse frequency. Then the second coffeebreak started at 1 pm. On that coffeebreak I just browse internet. After the second coffeebreak I began to orient Arduino example number 13. When clock hit to 1.50 pm, I packed my stuff and went to Matkahuolto waiting for the bus as usual. That´s the workdays last bus from Lapua to Kuortane. I left the bus at the same bus stop I come in workday mornings. Then I walked to home.

At home I first brew some coffee and then I heated some food. When I finished my meal and drunk a couple cups of coffee I went to browse internet to my computer. I read some news and reports about what has happened in Finland and worldwide. At 6 pm I went to shop by bicycle. I bought a bottle of drink and then I bicycled back to home. At home I watched tv about an hour or two and then I ate a supper. My usual supper is a couple of sandwitches and a cup of tea. After supper I went to sleep to by bed. That´s how my yesterday went.
