I triedall digital output pins to simply blink an LED, but when I meassure from the beginning to the ending of the circuit, I meassure only 4.63V. The output pins are supposed to have 5V. I know that on PWM pins the meassured voltage can be lower than the actual voltage, but therefor I tried ALL pins. They ALL are 4.60-4.63V.
Is this due to my cheap Multimeter? It is an Hapé MI-5.
