I need to build a turn signal unit for my bike. Going to use a micro and some relays. Relay for the left, relay for the right. Just need it to blink and turn off after so many seconds. I also would like to add a couple of pots externally to adjust the blink rate and the duration of the cancel. It this possible and if so how?
Thanks,
Newbie Jeff
Of course it's possible, but how will you power all this and how will you attach all this to the bike?
Quite achievable. I won't state the obvious.
See what others have done, never a bad place to start. Google
arduino bike turn signals
I just did, looks like a few ppl have done similar things. Read a few of the sketches they present and look at the hardware they use.

Hello Jeffie3,
I have Custom Dynamics fog lights that I installed on my Harley-Davidson 2003 FXSTSI Softail Springer and I also built a circuit board for it, this is NOT a turn signal circuit it is for blinking the fog lights either manually or latched switch. This is overkill for your question, but maybe you will like this project and edit it for your needs.
Here is the Arduino Script on paste bin. I have the schematic too if you are interested in soldering a proto board. HTH
You won't need relays if your turn signals will be LED's "low amps", just a microcontroller, with Mosfets, to do the blinking and momentary on buttons with a timeout in the script for the microcontroller. I used an atmega328 in my fog light circuit. HTH
There are statuary limits for the rate of flashing. You can't just make it variable to whatever you choose.
(a) Every indicator (other than a semaphore arm, that is an indicator in the form of an illuminated sign which when in operation temporarily alters the outline of the vehicle to the extent of at least 150 mm measured horizontally and is visible from both the front and rear of the vehicle) shall when in operation show a light which flashes constantly at the rate of not less than 60 nor more than 120 flashes per minute.
Going to use a buck converter. The bike already has a plug. It has a 12v connector on the plug. 12 to 3.3 to power the Arduino micro.
I looked at yours. Interesting. At this time, I'm just looking at doing a replacement for the expensive Harley box that is on the bike, that goes bad and costs way to much. I will switch to leds in time. I have found some drop in replacement leds. You just take the bulbs out and put the leds in as if it were a bulb.
Is the 12 volts from a battery or from a magneto?
Thank you for the information.
From reading I can read the resistance and set the blink rate according to the resistance? I think I will need to use analog to digital converters?
One of the features of the usual flasher units is that the flash rate changes if a bulb goes , a useful feature .
Bike electrical systems are also electrically noisy so you need to take care of that .
Not always, no.
Many motorcycles use the "other side" bulb as a return for the side in use.
Put a LED in and it will not work.
Thanks, Check out my Fog Lights Video Harley-Davidson Fog Lights My Circuit build - YouTube
It would be from the battery.
Thank you.
Nice
