I realized measuring with a multimeter that the drop voltage drops up to 2.2 volt in the rest of the pins after switching on the initial 4 leds, so i don´t have enough voltage to handle the rest of the leds. How could i work out this problem?I´ve tried using multiplexing and charlieplexing but it´s the same. So my problem is to be able to do the inicial effect with the leds using less pins or something like that.
Am i doing any wrong?
Yes, you will destroy your LEDs/Arduino/power supply of you keep on doing that.
If i measure again in the free pins defined before I see 2,2 Volts. I guess that it is normal, isn´t it?
Now if you measure the pins defined you will see 5 volts in each pin, but now you use 4 pins with a load in each pin. If i measure again in the free pins defined before I see 2,2 Volts. I guess that it is normal, isn´t it?
QuoteYes, you will destroy your LEDs/Arduino/power supply of you keep on doing that.Sorry, but I don´t understand how you took this conclusion.
May be all of yours are right. I was using a 2 coin cell battery in series with 5.5 v and 600mAh.
Coin cells can only supply a few mA
