  • Some notes

  • The ESP-32 board pins operate in 3.3v levels while the Gravity pH and EC sensors operate in 5V. I inserted a simple voltage divider to shift 5v to 3.3v levels on the signal pins. 
  • Step 1: 3D printing

  • To build a tower you will need to print the 3D parts shown on the left of the image. The "Sensors float" part is optional, print it if you want to use the pH and EC sensors. You will need 12 times the part: "Basket".  You can download the files...

  • I2C Sensors and debugging

  • I wanted to use a BMP280 I had in my parts bin for altitude measurements. I have used it in the past for a simple weather station and it works great! Turns out, it is even the go to sensor for Stratux, so I went ahead and plugged it in, activated it...
  • Cree Dimming Level

  • Flash the Arduino with the following sketch. This is also included as a file attached to the project. int last_level = 0; bool last_state = false; bool stable = false; int count = 0; const int cutoffs[198] = {/* 1*/ 833, 831, /* 2*/ 825, 823, /* 3*/...
  • Understanding how to disconnect the speaker

  • moThe big black device in the middle of the printed circuit board (PCB) is the speaker (aka buzzer, or transducer). You can see a little slit in the one side where the sound comes out. There is a back side to the circuit board that you cannot easily...
  • Address Bus

  • This last step is going to get REALLY tedious because the Address Bus has so many lines. But this is the last step and you should be done, so keep it up just a little longer. A0: 6502 Pin 9 to FLiP pin 13 A1: 6502 Pin 10 to FLiP pin 14 A2: 6502...
