Tools and Materials for Arduino
Nicely done! But I have a query here. Wont the pins 4 and 5 of arduino be required to source(CA) or sink(CC) more than 40mA of current when all the segments is ON(display number 8). Lets take one segment current ~ 10mA All 7 segments + Decimal point ~ 8*10mA =80mAWont the I/O pins fail at this point???
