Report As a major aspect of my HNC I was approached to Design, Manufacture and Test a circuit that would control both traffic lights and engine arranged on a model of the Kincardine Bridge. The determination I was given was that the circuit board could be no greater than 100 x 160mm and could cost close to  £50. Considering the detail I scanned for parts I would use to build the circuit ensuring the cost was under as far as possible (the complete expense was  £42.99). The second undertaking I embraced was to structure a board inside the necessary size (the last size was 89 x 74mm) however I ran into issues with the plan as a result of this there was an aggregate of 20 structures before the board was fit to be made, a portion of the issues are recorded beneath. SIL Reed hand-off pins were an inappropriate size Earth associations were absent LED’s were over-lapping The pins on the 7406 were associated the incorrect path round When the PCB was planned, the board was then produced. The assembling procedure can be found in Appendix page 2'. The following stage was to test and populate the board, progression testing was finished by utilizing a multi-meter to check for open and shortcircuits and afterward hand patching all the segments set up. The populace procedure took me around 3 hours rather than the 2 hours arranged as I needed to de-bind my wire joins as they were not of a satisfactory norm. The last procedure was to test the completed PCB, this was finished by testing the yields on the load up as they all worked first time I had no additional flaw discovering/troubleshooting to do. End As the circuit worked first time I demonstrated that I would be fit for experiencing ventures like this later on. The fundamental explanation behind the circuit working was the measure of time I spent at the structure procedure. This would set aside organizations cash, in actuality, as there would be no misuse of materials. I likewise feel that my undertaking abilities are improving, as there is a major distinction wager...
