This is a first cicurt board i made.
• A component 2x resitor of 560, 2x tranistor c547 1 yellow and 1 White leds power supply twelve volts and 5 voltage supply.
• Calculations
• A Technical Explanation : the 12 voltage supply through the wire to the board and it going to the resitors to the led and then to the tranistier then to the ground same as other leds and the resitor and the 5 volage supply the resistor to the resistor same path by in one way dicrections
• Test Procedure :testing the voltage drop the R13 =4.96v R14=9.33v R15= 7.14V R26=4.96v
LED 1 The white one is 310v LED 2 The yellow one is 5.28v . tranister 2Vce=00.4 Vbe=0.82 tranistor 1 Vbe=0.78 Vce= 0.4
• Problems :The first cucuit board i made it was totally stuffed up didnt even work so it kinda hard to find wt the problems was there alot of mistake i have done. well beacasue it my first time making the cirucit board wid two leds. my view i think it was the led been blown up beacasue i didnt do mch cutting on the board maybe that why it didnt work at all
• Reflection : i made a new cicuirt board this time scott help me to put in the right place before i think i put the led legs on the wronG way,but who knows.maybe the next time i should take it slowly and look at the chart that shows where to put ur component on the board and make sure the teachers check befre i carry on.
