- the blink has 2 lines to 2 analog ports, I think you meant one for left and one for right, right?
The double connector to the pin, consider it an extra freedom for the design of PCB.
Why are you using only 2 digits, in the Netherlands the speed limit is 120 so you need three digits I guess?
Looks like he's using a Nano, which has an on-board regulator. But, you're dreaming if you think what you're going to get is 12V. More like 10-15V, bouncing around all over the place (but generally around 13-14V) at runtime. But, that's technically within the limits of the regulator on the Nano.
I did a 2-digit speedo for my truck, that's more than enough for some vehicles
What's with the 3v3 going to the ABS speed sensor? For that matter what is this sensor?
And what's the warmup mode V going into AREF? And what is the warmup mode V for?
What sensor did you use on your project if I may ask?
My bike is fuel injected, it needs a few seconds before you can turn on the engine.
it needs a few seconds before you can turn on the engine.
That's a high forward voltage. The calculator does come up with 12R but you are multiplexing so each LED only get turned on for 1/8th of the time so I reckon you could go lower. However I've not got much experience with MUXing LEDs so maybe someone else can chip in here.
What is inside the "indicator turn light" block? Is that just lights or logic?Also, is the warmup signal logic or power?
What has that got to do with your gadget? It can run just fine motor ready or not.
