Diary of Making
First Lesson
One the first lesson of practical we were given a small packet with all the necessary parts for our project. The first bit of practical we did was solder the Picaxe unit itself onto the circuit board. After the Picaxe socket we needed to solder in the ULN2003A Darlington Driver socket. Then finally, we connected the 3.5mm download socket which means we can input our program from Picaxe Editor 6.0.7.2.
Second Lesson
In the second lesson of practical work I soldered the resistors into the circuit board, the resistors are 10k resistors, 22k resistors. The difference between the 10k resistors and the 22k is that the 10k resistors have a black line on them whereas the 22k ones do not have the black line and are a lot smaller. The resistors go where the diagrams on the circuit board show.
Third Lesson
Next I soldered the 100nF polyester capacitor to the circuit board, much like the resisters there is a white outlined box with saying C1 on it, Solder the pins into the white outlined box. The next part of the circuit is to solder the temperature sensor into it, this is here because I am doing a temperature sensor fan so this is the small green thing in one of the corners.
Fourth Lesson
Now you will add the battery pack to the circuit. The battery pack will be used in order to power the circuit and allow it to carry out its functions.
Fifth Lesson
Now you add the motor. to add the motor you need pieces of wire. solder the wire to the circuit board and then solder them to the plates on the motor. in order to test whether it worked place the 2 wires together and see if the motor spins.



How to Solder
 The correct way to solder is to place the tip of the soldering iron on the desired solder able place and then place the solder you wish to place next to the iron, melting the solder and joining up 2 things. the way you hold a soldering iron is like a pen however that may be because this ensures sturdiness and comfortableness while soldering. After soldering you should wipe of the soldering iron whith a damp sponge in order to get ride of excess solder on the tip.
