“I am working on some Arduino biometric designs perhaps for a new book. So far I have created the two line 1602 LCD display and now the Nokia 84x48 display. The Nokia display is more fun to work with since I can do a oscilloscope like display across the screen. I am working on writing code that works with both an Arduino UNO and with the ESP8266 or the “D1” board.
You can connect a NOKIA display easily using a header extender. You only need to connect five pins this way. The other two are power and ground and they use jumpers to 3.3 Volts and ground.”
