Using the phidgets pH probe and adapter board connected to the Arduino UNO R3. Arduino Connection From the user guide the adapter pin out is simply GND, 5V, and Analog Input: I connected the adapter cable to 5V and GND on the Arduino and I used the analog input pin A1. Continue Reading..

Formlabs makes a Stereolithography (SLA) High Resolution 3D printer called Form 2. (They are on their second generation model) I won’t go into the different types of 3D printers out there but the standard type most people think of is when you extrude hot plastic material and build up your 3D shape. SLA is quiteContinue Reading..

So I decided to get a couple of more environmental sensors for my pool monitor: The turbidity sensor essentially uses light to measure how clear the water is (simplification) and that can be used as a general metric on overall water quality. The UV sensor will be used to measure the UVContinue Reading..

I’m going to start off by reading the analog temperature sensor on pin A0 and displaying to the serial monitor. Then I will add the Nokia LCD and display the temperature to the Nokia display. Here’s the pin connections and setup of the analog temperature sensor with the Arduino UNO R3: Running the code theContinue Reading..

Currently using a Nokia LCD for the pool monitor display but I may want to swap it out for something a little bigger and that’s in color. Below is an example from someone’s online project of the Nokia screen in action: This might be good enough for my project but I want toContinue Reading..

I purchased my pH probe from phidgets and they have a great write up on how the pH probe (as well as ORP) works found here. Each type of probe has a reference solution that is used to measure the desired chemical property of the solution (in our case our pool water) withContinue Reading..

The water in your pool is just like the water in your house: you want it to be clean, clear and safe in order to swim in it. When we think about water quality for the purposes of drinking it we usually think of things like lead, arsenic and other harmful contaminants. If you wantContinue Reading..
