Wiring – Connecting the DS18B20 to an Arduino Connecting a DS18B20 to the Arduino is fairly easy as you only need to connect 3 pins. Start by connecting the GND pin to ground and the VDDpin to the 5 V output of the Arduino. Next, connect the middle pin (DQ) to any of the digital...
Hello, the tutorial "MAX7219 LED dot matrix display Arduino" It's great because everything is explained. All examples run on the Arduino Nano without any problems. Thanks for that. I have a question about the last example: "Example code for sprite text effect on MAX7219 LED dot matrix disp...
We choseArduino hardware, as it is open source, has a huge support community, and the hardware and software are easy to use. It is also a very inexpensive introduction to do-it-yourself (DIY) electronics. Due to its small size and price, we used theArduino Nanofor this project. The pr...
The Nano is available for around $8 US 2015 and I will need to investigate Bluetooth LE devices, but there are a number for less than $15 US 2015. Now this device will be less than $25 US 2015, if and only if, you do some soldering, etc....
(to emulate an additional serial port) because the Arduino Nano I am using for this project only has one serial port. The other library (LiquidCrystal595) is needed to control the LCD with only 3 pins. Make sure, if you use that library, to patch it according to the comments in my ...
Using either the custom PCB or manual wiring, connect the HM-10, DS3231 RTC and the Arduino nano together. If using manual wiring follow the circuit diagram ensuring the correct resistors are included. The custom PCB will save a lot of time and add more stability to the electronics so this...
