My first Android App

Hi everybody, i have found a cool website to built Android applications in a split second. Yeah in seconds you can learn how to code for your android device. Since i am not a fan of Apple's products i will not talk about IOS stuffs.
This is built by MIT and its one of the best product i found to develop for Android devices.



Within few days i learnt the basic and later built an wonderful app to control my Bluetooth modules.
This is how the coding looks like. Look how easy it is, just like a puzzle. For advance projects like these you need to refer to Android guide to know how some phone modules work with the command.


Here is some pictures of my app.




This a good and useful software for kids and schools. Instead teaching bullshit we can teach this to increase mind activities / practical involving others to learn coding for there daily use. For example i built this app to switch on/off light, you can built an app to monitor your plants health.
I am also working on such a project now a…

Solution for avrdude: stk500_getsync(): not in sync: resp=0x00

Its been a while that i have noticed an error that sometime frustrates. When i first start using Arduino Uno and flash custom ATMEGA328P firmware i have faced tons of problems and each of them ease my work when i found a cause and solution for that.
Most of Arduino users faced this and thousands of posts were in the forums related to avrdude: stk500_getsync(): not in sync: resp=0x00 error. Some solutions in the forums are not much solved the issues. Earlier i faced this when i built a custom PCB with ATMEGA328P-AU.
 After flashing the firmware via ICSP (In circuit Serial Programming) Then i used FTDI serial to load the sketch. Finally the error occurs and the whole project came to a halt.


I have spent most of the time troubleshooting and found solutions for it.

I will state what i have found, which cause this error normally.

Wrong device selected from the IDEPCB/Circuit designing issues.FTDI module / Driver & software issues.Wrong device selected from the IDE

Most cases by mistake …
