Easter has been quite productive for me, this is project 3 out of 4 is rechargeable battery powered arduino clock with temp and humidity function. Nothing fancy, but highly practical and accurate. The code is a mess, but i have shared it down below, i know someone out there can clean it up and make it more efficient, but for now, its working and doing what it needs so, show the temp and the time.
Hardware is kind of inefficient for this task, arduino mega and 3.2″lcd are both overkill and power hungry. There is an RTC and temp humidity sensor, 18650 battery, boost and charge controller. As usual i did a really crap job at cutting the hole out, I really should have done this in the CNC, I might even make a how to video on how i do that later today.
