can we make the timer using the push switch and relay for the digital timer with tm1636 ?

Good idea Ravi, I'll add it to my todo list.

VIN is 5V, not 3.3V as you said.

You should use a resistor on the LED line.

hey Yarden, the diode has a forward voltage of 4V so there's no need for the resistor. Check my reply to the comment from this video: kzbin.info/www/bejne/ZoPXqJeHj7eng9E My fault that I forgot to add diode datasheet info to the description of the video, gonna do it now ;)

Hi, I have configured pin D1 and D2 as input to detect 3.3voltage connected to these Pins, So my expectation is, when i read pin it should return HIGH if and only if wire connected to Pin is 3.3v, but it remain either low or high. How to add external PULL_DOWN to these pins, i tried 10k and 4.7k but did not help.@@tomasztarnowski4434

can resistor be installed in nodemcu expansion board?

USB and VIN is +5V not +3,3V
