This paper is about how to write Libraries for DHT11 (Temperature & Humidity Sensor) and 8x8 Dot matrixLED (1088BS). DHT11 has single data pin which can be used as bidirectional pin, so before reading DHT11 Arduinohas to send the signal for getting back data from DHT11. DHT11 provides 40 bits (5 bytes) of data. 2 bytes for integraland decimal part of humidity, 2 bytes for integral and decimal part of temperature and final byte will providechecksum.The pins of 8x8 dot matrix LED needs to be identified first. Once the pins are known the library can be writtenfor it. For this pape,r 8x8 dot matrix LED doesn’t require driver circuit. 8x8 dot matrix LED can be connected throughwires with the port pins of Arduino. It can display temperature up to 2 digits means 0 to 99 ℃
