Led Lights Walking with 7 points

Led Lamp walked seven this point the intention is to walk with 7 LED light output or output, taken from the IC output line associated with LED lamps positive leg (anode) while the negative foot LED (Cathode) is connected directly to ground or negative voltage. If we can set up led by the principle of series-parallel then we can arrange the letters run with seven canal as well. In assembling the initial rangkian canal connecting each 1 to 7 of IC 74 164 to the foot LED (+) and foot LED (-) rolled into one and then plug kekutub (-) of the voltage source. Use a voltage source of 9 (nine) volt. It can also be the voltage 12 (twelve) Volt but circumstances led eventually fired irregularly. Please try it. PCB Lay Out To Line to Click here
