Esp-32 web socket/Rpi master to Arduino slave
Budget: $30 – $250 USD
On the Esp-32 we need to get a web socket operational with 6 digital i/o pins ( on/off ) and 2 analog pins (slider bars for potentiometers) and 1 pin for the touch sensor that is built into the ESP-32. You can go to random nerd tutorials.com and look up web server or web socket and see what I'm trying to get done here...
Now on the Rpi master to Arduino slave we just need to set up a simple I2C/serial communication situation with a code that for starters operates 6 digital i/o pins and 2 analog pins for potentiometers using millis ...key detail no delays written anywhere in code and .....here's where I will need your expertise cause can I access Arduino serial monitor from Rpi terminal window ? Specifically we are using a sixfab 4g hat on our Rpi3b++ 's and it's a headless setup lite Opsys so we really want to avoid having to type full grammatically correct sentences everytime we want to turn a pin high or low. Think on it please and let us know... Our budget is $75
