That seems it move forward, but it returns the undefined.

See here full snippet:

As you may tell that I'm very new to this. This feels like I'm trying to push a wooden triangle in the circle hole without knowing what those are.

I followed the tutorial and it worked but when it comes to me trying to move the motor, it didn't work. Any advice?

I truly appreciate your time!

Hi Mabe,

Thank you so much for your time!

Yeah, I ran I2C1 too. See here that I just did 15 minutes ago before began my level 5 search in Google :P

print(I2C.find(D20));
I2C1.setup({ sda: D20, SCL: D19 });
I2C1.setup();

I get error like this:

Uncaught Error: Unknown option "SCL"
 at line 1 col 34
I2C1.setup({ sda: D20, SCL: D19 });

also when I wrote to robot to see if it will at least move the right wheel by doing this:

I2C1.writeTo(0x08,1)

Seems no luck. :(

Hi everyone,

I'm very new with Espruino and Javascript. I am learning Javascript from w3_school

Microbit...on other hand...it seems that everything is explained on Microbit

As this is concise and clear tutorial however, I noticed that there is no information anything about write digital, read digital or move the motor using smart_cutebot

I tried I2C and it says I2C.writeTo() is not found.

I've been trying new stuff on this microbit and I feel like I'm nowhere near to the start one.

So I come here to seek for your advice, or suggestion.

Super beginner on Espruino and wants to learn more :P also loves to talk with new people online or irl!
