The LCD module used in this project is JHD162A. This is a 16×2 LCD module with 5×8 character dots. The LCD module has a 16-pin interface. The LCD is interfaced with Arduino in a 4-bit mode. The pin 1 (GND) and
I built an arduino Uno R2 temperature datalogger using the Adafruit data logging shield, 6 ds18b20 onewire sensors (using the DallasTemperature library) and an Adafruit RGB 16 x 2 color LCD. I got a lot of help from Adafruit_support_rick on getting everything working, thanks: other who mig...

Demonstrates the use a 16x2 LCD display. The LiquidCrystal library works with all LCD displays that are compatible with the Hitachi HD44780 driver. There are many of them out there, and you can usually tell them by the 16-pin interface. This sketch prints "Hello World!" to the LCD and ...
±6.144V / (2∧16 – 1) = ±6.144V / 32767 = ±0.1875 mV 与Arduino UNO 内置的 10bits ADC,每步 4.85mV 相比,精度提高了 25倍。如果PGA 设为1x 增益,即测量范围降至 4.096V,精度为 ±0.125mV,如果 PGA 设为16x 增益,测量范围降至 ±0.256V,精度可达 ±0.0078125mV。简单来说,PGA 增益越大,...
