ADS1115 16-Bit ADC - 4 Channel with Programmable Gain Amplifier#1085 For microcontrollers without an analog to digital converter or when you want a higher precision ADC, the ADS1115 provides 16 bit precision at 860 samples second over I2C. The chip can be configured as 4 single ended input channels, or two differential channels. As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single differential signals to the full range. We like this ADC because it can run
#1085
For microcontrollers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1115 provides 16-bit precision at 860 samples/second over I2C. The chip can be configured as 4 single-ended input channels, or two differential channels. As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range. We like this ADC because it can run from 2V to 5V power/logic, can measure a large range of signals and its super easy to use. It is a great general purpose 16 bit converter.
The chip's fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet. Interfacing is done via I2C. The address can be changed to one of four options (see the datasheet table 5) so you can have up to 4 ADS1115's connected on a single 2-wire I2C bus for 16 single ended inputs.
To get you started, we have example code for both the Raspberry Pi (in our Adafruit Pi Python library), Arduino (in our ADS1X15 Arduino library repository) and CircuitPython. Simply connect GND to ground, VDD to your logic power supply, and SCL/SDA to your microcontroller's I2C port and run the example code to start reading data.

Stopped working within 3 days
Color: Blue
Worked for 3 plays. My 11 week old puppy loved this item. Unfortunately, it only lasted 3 tries before the motor stopped working. $30 for a total of 30 minutes over 3 days is robbery! I'd look at another vendor for the same type of item. We charged it after each attempt but now the motor won't turn on.

Item was returned
Color: Blue
Used it one day and partially the following day. Put on charger. Never worked again. My dog played with it but returned it as defective.

Not for super chewers
Color: Blue
This ball seems to be of good quality; has held a charge well and is easy to use. Sadly, the cover lasted less than 15 minutes with our dog.... not for aggressive chewers for sure. Pretty funny to watch the hound dog jowls shake though.

Great fun for dogs!
Color: Orange
Two of our dogs really love this! It caused a lot of barking and chasing and running around trying to grab it. It's really funny to use the remote to control it (and especially make it stop when things get a little too chaotic!) It feels durable even when pawed and bumped into and stepped on. The battery life seems good. I plugged it in overnight to charge so not sure how long it took to charge, but it has lasted quite a while with the dogs playing with it and still doesn't need a charge. It's easy to screw off one side of the ball to plug it in to charge. The size is a little bigger than a tennis ball I would say and has a soft texture.

It doesn't work.
Color: Blue
The two halves of the ball shell come apart again and again when the dog plays with them. When it is time to recharge the core, it will not take a charge. The dog loves it, but it's unsafe to play with.
