If you want to change time, click on select button(button-2 in video) keep clicking until you see option "Time". Momentary press is used to display menu items and long press is used to get into menu item also to save and exit. Select button works as menu which supports momentary press and long press. On press back clock can display day, temperature, humidity etc. Two momentary switches are "back" and "select". Momentary switches use 220ohm resistors and DHT sensor uses 10K ohm resistor. We will design our circuit based on below diagram. MDF board, paint, drill machine, screws, glue gun etc.Female to female jumper wires, normal wires.In this article we will learn how to make a digital clock using Arduino nano with below features:
