"The display works with the Adafruit_SSD1306 Arduino library."
"I cannot think of many (if any) useful projects that need a small screen like this and can run on the Arduino UNO R3 after this display takes up most of the variables usable memory."
"The wires used are from this product link: Kalevel® 120pcs Multicolored 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Wires Ribbon Cables Kit."
"I have multiple set temps for the different filament types and the screen displays which filament it is set to."

"Diymall 0.96" Inch I2c IIC Serial 128x64 Oled LCD LED White Display Module for Arduino 51 Msp420 Stim32 SCR. This little OLED Display Module is easy to get up and running in Arduino and looks SO great!"
"Best little screen ever."
"There are other mono OLED displays that cost less (thus 4 stars), but this little display works pretty good."
"I really wish I had paid closer attention to the product description and some of the other reviews because this display really is tiny."
"The fact that it's i2c is perfect for an ongoing project. Not as bright as another OLED screen I had recently, but that one conked out on me after a day, so I'm not complaining."
"This OLED screen is everything that I wanted."
"The biggest plus is it takes 4-wires to connect to the main unit...the other 2x16 takes (if memory serves me right) 9-wires and depending on the unit you choose another 3-4 jumpers."
BME280 Pressure Temperature Sensor Module with IIC I2C for Arduino. Descripton: The BME280 is a great new chip which was originally designed for the next generation of smartphones. With an I2C connection you have access to enough weather data to make some pretty good predictions for your local area.

After loading the Adafruit library I changed this line in the example script Adafruit_BME280_Example.py to use the correct i2c address."
"The pressure and humidity seem to be fairly accurate."
"I had some cheaper sensors (4PCS DHT11 Digital Humidity Temperature Sensor /Arudino) but they didn't work past 0*F so I got this one even though it is a little more expensive it works great and has the added pressure reading."
"Wish these would be a bit cheaper but I only need one of them, the rest of my boards will be fine with DHT22s for temperature and humidity."
"Great little sensor when you need Temp, Humidity and Barometer on a single chip!"
"It works as a charm!"
"Used the embedded adventures library, soldered on the header and everything worked."
"I can't recommend this."

"Easy installation."
"It works."
"Great product, fast service."
"My infloor heating system had stopped working and these replacement parts were easy to install and get my heating system working again."
"exact replacement and works as it should, the old one would open the valve but would not signal the circulator to kick on ,"

"These are nice and make things more simple when wiring, however the plastic could be of a little better quality, be careful when mounting these or you will crack them, also the caps dont stay on very well."
"High quality, covered connections with protected jumpers offer flexibility to these compact buss bars."
"These small terminal blocks will help me organize and simplify the wiring in my classic Dodge Charger."
"perfect!"
"These terminal strips worked out very well for my project."
"Excellent bus bar/terminal strips for the money."
"They make everything look 100% neater, it's easier to add devices to my solar array, and overall it's safe in my opinion especially since it has the covers!"
