* Outlook of kit blueprint / sketch
* Shows what is suppose to be the copper side of the printed board with all of the devices / components in their correct spots and polarity direction * Shows the exact length and width of the kit, the printed board, and of the battery case * Titles show and state which component is which |
* First look of printed board (copper side) * All components of circuit are in their places on the board and are soldered * Before exactly putting the components in their places as shown for its schematic diagram and on the sketch, I would have to look back and forth at the sketch and the copper side on the board so that I am putting the correct components in their correct spaces as shown in the sketch *Sketch is supposed to stand for the copper side of the printed board. * Second look of printed board (non-copper side)
* Shows the components of the circuit * Components are in the correct places as shown on the sketch * The red and black wire that is to connect to the 6VDC power source on the far left of the board were accidentally mixed with each other in their places on the board * Today (January 6th) in class, I was able to connect the circuit to the power source on the table where I sat at. I set the power source up to 6 Volts and the speaker made the loud noise it was supposed to by connecting the positive wire from the power source to the black wire on the printed board, same thing with the black wire form the power source to the red wire on the printed board, since that they were mixed with their places on it * Successful Test * Third look of printed board (copper side) * All of the copper along with the soldered components to the printed board are all soldered * Stronger electrical connection * After all of the soldering was done, today (January 6th) in class, I was able to connect the circuit to the power source on the table where I sat at. I set the power source up to 6 Volts and the speaker made the loud noise it was supposed to by connecting the positive wire from the power source to the black wire on the printed board, same thing with the black wire form the power source to the red wire on the printed board, since that they were mixed with their places on it * Fourth look of printed board (copper side) * Had to be de-soldered because of too much solder on each component (big goops of solder = no strong electrical connection) (LED was lit, but the speaker was not making any sound) * Had to be re-soldered so that the soldering on each of the components are not too big and so that they can have a good electrical connection (Hershey Kiss shaped = strong and good electrical connection) * Four AA batteries (1.2 Volts each) are connected and soldered to the circuit board and there is no sound coming from the speaker * When the circuit board is connected with the Power Source adjusted to 6 Volts the speaker works * 1.2 * 4 = 4.8 (no sound) * 6 = 4 * 1.5 (speaker sounds) * There isn't enough voltage to activate the sound! * Final look of printed board (non-copper side)
* Switch is activating the light to turn on but not activating the speaker to make a loud sound * When I put my finger on the speaker in the center as shown in the picture, I add a little bit of pressure to it. As I do so, the speaker will make the loud sound it is supposed to * This proves to me that the amount of voltage is not the problem at this point, but it was something else I am not quite seeing in it * The problem was that the solder on the wires of the Push Button Normally Open Switch (red) was connected together, not making a good connection * Also the screw on the bottom of the speaker needed to be screwed in a little bit. |
