I want to make a binary clock and I found a place with info of "how to" do it but since I'm total noob at electoronics I need some thing clearing some stuff
1st here's the link
http://www.instructables.com/id/LED-Binary-Clock-20/
So far I'm still in a process of obtaining the stuff, mostly from ebay, and on a list is this item:
matching resistors to apropiately drive your LEDs at 5 volts (you can calculate the value here).
But how do I find matching resistors? I know he put the calculator but the seller doesn't give any specs. I was thinking of buying these LEDs (yellow ones)
https://www.ebay.com/itm/100-500-10...ow-LED-Light-Bulb-Emitting-Diode/201863138713
Then he also lists: 220uf caps -- I've seen that some vary in price, you think these will do?
https://www.ebay.com/itm/10PCS-220UF-50V-105-C-Radial-Electrolytic-Capacitor-10-12mm/321424253165
On the 16Mhz crystal he says to get caps (22pf). Is this it:
https://www.ebay.com/itm/100pcs-22p-22pF-50V-0805-SMT-SMD-Capacitor-Cap-Brand-New/251169384898
He lists: 100nf caps (104) -- but what is "(104)"? would these do?
https://www.ebay.com/itm/1pf-100nf-...itor-Assorted-Kit-Assortment-Set/120982871681
Also I can't decide on breadboard. Do you think these one will do?
https://www.ebay.com/itm/10PCS-5x7cm-Bakelite-DIY-Prototype-Board-PCB-Universal-Breadboard-High-Quality/200979359499
or maybe one of these
https://www.ebay.com/itm/10PCS-Double-Side-Prototype-PCB-Bread-board-Tinned-Universal-FR4-2x8cm-9x15cm/263518832138
For power supply he said 7.5 to 12 volts out, do you think this one will do (EU 12V 2A)
