Checked the polarity on the LED's and even switched them around, 560 ohm resistor on the cathode side of the LED. Ran a 24 awg jumper to my bread board. Circuit is in tack based on ohm test using sound setting on my ohm meter.
On my arduino I setup for the single LED blink program and connected it to pin 13 cathode and grd on the anode this works fine. I then wanted to do the next step of the tutorial with the alternating LED's. For this I connected up the LEDS from Pin 2 - 8 and did the setup, did not work. I then checked my connections and resistors all good. Connected jumper from pin 13 Digital output to breadboard placed LED and jumped back to ground on arduino. Still did not work. LED's work fine on the arduino.
I have been trying to identify new things on an old pc power supply I might be able to use with test etc. on my new Arduino uno. I found some voltage regulators, PWM, resistors etc. What are my chances that I can use stuff like this, and be able to use small componets like on the Arduino? I am old school analog and only have a single power soldering iron?
I received a parallax basic 2 stamp and accessories several years ago from a friend. I was unable to use it as program was based on windows software and RS232 connection. Can this be used for arduino programming? I also thought i saw parallax stuff being used but am very interested in the arduino software as it is open source and I am an old Linux user in my previous job.
