Latest Arduino Driver 12 interface/outdoor LED display/led dot matrix panel/led Unit Board

CauseThe existing drive LED display data, better than the only this. But it drives the 08-interface indoor display, and I'm going to drive a 12-port outdoor display. The difference between the two screens is that the outdoor screen lattice is sparse, and both of the scanning mode, the driving style is not the same. It took me an afternoon to find out the way it was used, so I shared it with you and I hope you don't have to detour.Material preparation

LDO current regulator for power LED

brightness we had to regulate the power consumption of the LED by controlling the current. Wikipedia [1] shows a simple circuit of the transistors and three resistors limiting current independent of supply voltage . We change the circuit by removing resistor R2 which are not really needed. What's about dropout voltage? Clearly, there is VCEsat of Q2 which can being in the area of 0.2 V at current around 1
