DS18B20 digital thermometer chip. Here we describe the DS18B20 chip which measures the temperature and transfer it serially to a microcontroller.
DS18B20 communication with an AVRmicrocontroller. Here we present the way the DS18B20 communicates with an AVR microcontroller.
DS1302 timekeeping chip. Here we describe the DS1302 chip which provides the time and date serially to a microcontroller.
DHT11 Humidity and Temperature Sensor. Here we describe the DHT11 sensor which measures the humidity and temperature and the way they are transferred to the Arduino platform system.
BMP180 Barometric pressure sensor. Here we describe the BMP180 sensor which measures the barometric pressure and temperature and the way they are transferred to the Arduino platform system.
The MAX7219 and MAX7221 common cathode display drivers. Here we describe the integrated circuits MAX7219 and MAX7221 which are serial input common cathode led display drivers.
