4 Digit 7 Segment Display Shield For Arduino Nano

4 Digit Multiplexed display shield for Arduino Nano with on board 2 tactile switches and LM35 temperature sensor. This shield helps you to develop many projects that require 4 digit display. For example a thermometer can be made using on board LM35 sensor.  7 Seven segment multiplexed display is a tiny board and has been designed around Common cathode 4 digit Display. Display has 12 Pins. The board is provided with current limiting resistors on all LED segments and 4 NPN Transistors to drive 4 digits. This tiny board directly seats on Arduino Nano.  Nano analog pin A0 connected to LM35 sensor, A1 and A2 connected to Switch 1 and switch 2 with pull down resistors. Digital pin D2-D8 connected to displays segment A-F, Digital pin D9 connected to DP of display, D10-D12 pins are associated to Digit 1-4 common cathode.
