You might need to add some diodes from power supply, but I think that's already grounded. and D7 or clutch switch pin is protected with diode, so 12v positive will not flowing through.And for the Mosfet, I'm not touching this project since last update, because relay still worth it for long term use. (And yes, mine still working fine) also, working for another projects.

output from Arduino to relay (I forgot maybe pin 5) add resistor to it and to ground

If you want to use low level relay module, you need to change digitalWrite command from LOW to HIGH, and HIGH to LOW on the bottom. If you're using relay with transistor (not a module) it will run correctly.

Did you follow the schematic? Make sure you connect everything correctly and the relay shouldn't turned on if pin 2 not connected to the ground pin. I'll give you pict that shows you what should you change on the code. This is the code for no display out.

Yes, it does. IF you're using low level relay module (5v) like this : Low level relay module&safe=strict&source=lnms&tbm=isch&sa=X&ved=0ahUKEwiP7dSS_5rfAhUMUI8KHVJxAqoQ_AUIDigB&biw=1100&bih=1804&dpr=2.08

if your bike using FI system, you need to connect it to the coils. If there is 4 coils, you can use 2 DPDT Relays with 2 transistors (don't forget to add diode. *read schematic). how to connect? unplug 1 cable from the coil (for the example coil no.1), then connect it to the COM1 pin on the DPDT Relay. Connect NC1 pin into the terminal on the coil1 that last time connected directly to the cable on your bike. do the same steps to all of your coils. if you use DPDT, on the coil2, connect it to the COM2 and NC2 (DPDT Relay has 2 pole 2 throw). or you can use 4 SPDT Relay (like on the schematic.) with more transistors and diodes. 4 relays, 4 transistors, 4 diodes (to protect the transistors from voltage collapse from the relay)

Nope, I'm using TDA2822L.tbh, I don't really care about the last letter, at least they has a same function that I want.You can use both of TDA2822H or TDA2822L.The only differences is the maximum voltage input and power output. (i guess)

You can do that, but you need to make sure where the cable goes.

did you mean Engine with 2 Cylinders? If so, you can use DPDT Relay or use 2 SPDT Relays with 2 Transistors and 2 Diodes

Does it works? Hopefully it have long life sir!

That's used for preventing your motorcycle turned off when using clutch, so the Quick Shifter will be disabled when Clutch was pulled.

I've already tested using Mosfet, it can't handle the current and blown. No idea why, but I already put diode on it.I will making circuit update for this project, and might take some time because need to remake the video for it.

Sorry mate, I can't send you the I2C Library. Gmail blocked the file :(If you wondering what version I used, I'm using v1.2.1 Library, also I updated the gist and adding some links to download the libraries :)I'm really sorry for that library and very long time to reply :(Best regards

Sorry for that, but I forgot where I got the library from :(Maybe, I download it from github page.But I still have the library.. I can reupload it for you if you wantRemember the library is for I2C

Don't forget to remind them to not listen loud music for long periods, it can hurt hearing :)

mantap gan...
