I actually need to be built an atmega328P ( or simpler ) as a timer to close a transistor gate to power a sensor. The target is to wake up few seconds (measure + send data via 2.4 GHz arduino module ) each 6 hours (around ) and then go back to sleep. I've linked the set up I've made, that actually works but sometimes the timer keeps awake. Then I'd like to have a more stable solution.

Hello, I am Anthony from Sri lanka. I have 7 years of experience in the field of electronics. Currently I am working as a full time freelancer and I have state of the art electronic lab. Why you should hire me ?? *** I have state of the art electronic workshop. *** I have worked with many micro controllers and modules. I have developed my own libraries to work with most of popular modules. *** My workshop is equipped with, ** PCB printing materiels ** 3D printing (Both DLP & FDM) **Various kinds of breakout boards **Qualified developers *** At some point after creating the prototype, if you are willing to take your idea to commercial level (mass production) I can help you with that since I have many reliable contacts in China. I would like to start working with you in order to bring your idea into reality. Please contact me if you are interested. We can discuss more. Thank you Anthony

Your idea is OK, you just need to use a MOSFET to switch the +5V on/off and make a few changes to the sketch. Breaking the ground connection with the BD237 can cause problems. I can provide a simple schematic showing you what to do and a new progrm. Which Arduino board are you using for the Timer? Regards, Jim
