ESP-01 and Arduino Controlled Robotic Hand - Code Problems
Posted: Wed Nov 18, 2015 2:28 pmHey guys,
I'm hoping you can help me figure out how to make this project work. The idea is that we build a sensor glove which helds five bend sensors, an arduino nano and an ESP8266-01. On the other end we have an InMoov 3D Hand, five servo's, another arduino nano and another ESP8266-01. The set-up works flawless and the only problem we get is with the ESP's sending data to one another. We now do it on the way described in the code below:
Sender:
And the serial output would look like:
Receiver:
And the serial output would look like:
Does anyone see what the problem could be? Or does anyone know if there is another way to send this data? And how fast can I make this sending?
