Some good but more bad
This was a really simple and great app at first it worked, The controller would definitely have been worth the 5$ if it worked reliably, then it didn’t it only works if Arduino is connected to computer. This app cause me a lot of headache thinking something was wrong with my Arduino circuit, testing every wire and making sure it’s at right voltage to only find out hours later that it was the app acting up. It’s already bad enough that iOS is really dodgy with Arduino, just download a hm10 reader on App Store and manually write the commands, so much better.
