Here’s how I worked with the material! Thermochromic paints that were available: (http://www.cornelius.co.uk/search) Chromicolor® AQ Ink Type 10 Magenta colour change occurs between 8-16C. Chromicolor® AQ Ink Type 27 Magenta colour change occurs between 24-33C.

Serial communication can be very important for troubleshooting, to see what bits of the code are working properly and which aren’t. It can also necessary for extra functions like for example communication data to […]]]> https://nerding.at/course/101/?feed=rss2&p=1592 0 https://nerding.at/course/101/?p=1587 https://nerding.at/course/101/?p=1587#comments Thu, 03 Jul 2014 16:20:18 +0000 http://nerding.at/course/101/?p=1587 Better late than never: These are notes I took for myself, that helped me understand how a voltage devider works. I think it’s quite an important thing to know, because components like potis are based on it and a lot of other components need to be combined with a second resistor to work as a […]]]> https://nerding.at/course/101/?feed=rss2&p=1587 0 https://nerding.at/course/101/?p=1569 https://nerding.at/course/101/?p=1569#comments Wed, 02 Jul 2014 07:54:58 +0000 http://nerding.at/course/101/?p=1569   Hey everyone. I found this video which explains in detail how to get the solder joints right. I’ve had some difficulties with good soldering, and Maggy you said were starting. This video was quite helpful]]> https://nerding.at/course/101/?feed=rss2&p=1569 0 https://nerding.at/course/101/?p=1353 https://nerding.at/course/101/?p=1353#comments Tue, 17 Jun 2014 08:11:03 +0000 http://nerding.at/course/101/?p=1353 You can go to http://www.kobakant.at/DIY/?p=3742 to get the detail instruction. another tutorial>> http://highlowtech.org/?p=1695 https://github.com/damellis/attiny/archive/master.zip There are many kinds of ATTINY, but today, we use ATTINY45 or 85 You can also get a USB programmer for ATTINY45/85]]> https://nerding.at/course/101/?feed=rss2&p=1353 0 https://nerding.at/course/101/?p=846 https://nerding.at/course/101/?p=846#comments Sun, 11 May 2014 21:01:28 +0000 http://nerding.at/course/101/?p=846 We have tried Servo and DC motors already. (Here I’m gonna concentrate  a little more on DC motor, since servo is already described in Mika’s course note. ) The difference between the two is: Servo: * You can control the orientation and the angle of movement quite precisely. Normally the angle varies within 0 & […]]]> https://nerding.at/course/101/?feed=rss2&p=846 0 https://nerding.at/course/101/?p=837 https://nerding.at/course/101/?p=837#comments Sun, 11 May 2014 18:23:01 +0000 http://nerding.at/course/101/?p=837 What is Flex sensor? Flex sensor, resistive sensor also works as the potentiometer. It is a flexible strip that changes its resistance when bent. The bigger curvature creates the bigger resistance. How it works? One side of the sensor is printed with a polymer ink that has conductive particles embedded in it. When the sensor […]]]> https://nerding.at/course/101/?feed=rss2&p=837 0 https://nerding.at/course/101/?p=796 https://nerding.at/course/101/?p=796#comments Sun, 11 May 2014 12:48:28 +0000 http://nerding.at/course/101/?p=796 You can divide the voltage by using 2 resisters. If you have 2 exactly same resistors, the voltage gets half in the middle, like the first diagram. As the ratio between two resisters changes, the voltage you get in the middle (between the resisters) changes accordingly. As the analog input pins are reading the voltage […]]]> https://nerding.at/course/101/?feed=rss2&p=796 0 https://nerding.at/course/101/?p=787 https://nerding.at/course/101/?p=787#comments Sun, 11 May 2014 12:39:44 +0000 http://nerding.at/course/101/?p=787 PIR stands for Passive Infrared This sensor detects motion by measuring changes of heat in its surroundings.  It is easy to connect if you follow carefully this few steps. For this Tutorial you will need: 1 Arduino Board 1 PIR Sensor 1 10kΩ Resistor Cables This is what the sensor looks like.

We use the constants HIGH (on) and LOW (off) since this makes it easier to read code. Digital pin always gives the output power of 5V when HIGH and 0V when LOW. The pin need to be configured with pinMode( ). […]]]> https://nerding.at/course/101/?feed=rss2&p=746 0
