I can't get the Otto DIY robot sketches to upload to my Nano. When I try it starts to write and gets anywhere from 12-50% and then stops with a "avrdude: stk500_recv(): programmer is not responding" error.
I was hoping to build a bunch of Otto robots with the students at my school. I bought clone nanos on Amazon (eMakefun Nano) to keep the price down and I can't seem to figure out if my problem is due to being a clone or what.
I am on a mac running High Sierra and have used the Web and local version (1.8.6). It took me a bit to get the right ch340 driver, but I finally got it connected. I even powered it externally with Lion batteries in case it was running out of juice (doubtful because I don't have any sensors attached or anything yet).
Can anyone give me advice? Is it simply an issue with a cheap clone with a cheap USB-Serial chip and I need to get real Arduinos for this project?
