Experiment 12 “Joining Two Wires Together” is the introductory step into soldering and also the start of chapter 3. Depending on what you currently have on hand in your lab. In order to move forward, you will need to purchase a few more items both equipment and component wise.  For what it is worth. This experiment is designed to get someone who has not soldered before some experience with the

Experiment 11 “Light and Sound” is a continuation of Transistors.  The experiment itself is broken up into several phases whereas the first consists of a circuit that flashes an LED on and off for approximately one second. The next phase of the circuit introduces a coupling capacitor which in turn creates a pulsating effecting via the implementation of an RC network. The difference between the two is that the LED

AVRISP MKII Tutorial – The setup

So, you finally got a hold of an AVRISP MKII and have no idea what to do next .  Well lucky for you the setup and overall configuration is a lot easier than you might think. This mini tutorial will demonstrate how to flash an AVR chip via the Atmel Studio 6 IDE.  If you do not have Atmel Studio installed you can download the IDE from here. Of note,


Exercise ten, “Transistor Switching”.  This exercise introduces a very important component which has characteristics similar to the relay.  Whereas both components can switch the flow of electrical current. That said, the documentation explains the ins and outs of transistors, in that they are naturally off until turned on; considered a limitation.  Relays on the other hand offer more switching options, i.e., can be normally open, normally closed, or utilize a


Exercise nine, “Time and Capacitors”.  This exercise demonstrates how one can measure time by simply placing a capacitor in series with a resistor.  The importance of this concept is related to the “time constant”.  That said, by placing a capacitor and resistor in series, the amount of time it takes for the capacitor to charge will be much longer than if both components were placed in parallel. To fully implement


Exercise eight, “A Relay Oscillator”. This exercise is a slightly revised version of exercise seven in which the direct connection was between the push button and the coil.  In exercise eight, the voltage arrives at the coil as a result of traveling through the contacts of the relay.  Therefore, when the push button is depressed, the contacts of the relay feed the voltage to both the coil and the leftmost

Exercise seven “Relay-Driven LEDs”.  This experiment introduces the Relay component and is used to drive two LEDs.  The heart of a relay is basically an iron core wrapped around wire.  The electricity running through the coiled wire will produce a magnetic reaction,  triggering an internal lever that closes two contacts.  During this process the relay is said to be energized, allowing a low voltage signal or low current to travel

Exercise six “Very Simple Switching”.  Looking back to exercise four we covered how to turn electricity into a functional property and lit an LED.  This exercise follows up that concept and is the beginning stages of controlling electrical power via switches. Putting together the discrete components is quite simple but can feel a little tedious without using a bread board.  I could imagine that someone who has not done this

Exercise four “Varying Voltage” is an introduction to the manipulation of voltage via a pot (potentiometer). One of the initial requirements of this exercise is to dismantle a pot and perform a visual inspection of its inner-workings.  Personally, I am not a fan of ruining a perfectly functioning component. However, if you are careful, it is pretty easy reassembling the pot. A DMM is used to reveal the resistance bandwidth

Exercise Three “Your First Circuit”.  At this point we finally begin to make something that resembles an electronic circuit.  The purpose of the experiment is to show you how to turn electricity into a functional property and power a light-emitting diode. One of the key take-a-ways from this experiment is what is learned about the general properties of an LED.  The longer wire (Anode) is the more positive side and
