Hello, I am thinking about putting this picaxe circuit together, however, with me being a newbie, I dont understand the purpose of the Darlington Transistor Array.
It seems to me that you could just connect the Picaxe outputs directly to the LED's, instead of going through the array. Then I thought perhaps the array boosts the current, but there does not appear to be any power going into the array ?
Can someone please tell me what the transistor array does ?
thanks kindly
