Arduino ATTiny85 does not blink LED. Programmed with Arduino nano

Hi!

 

I have an ATTiny85 and I want to start with the blink LED sketch but it does not work. Attached is the wiring:

I followed these instructions: http://forums.4fips.com/viewtopic.php?f=3&t=1080 for wiring, burn both bootloader and LED blink sketch with an Arduino nano as programmer (excepting I'm using 1.8.1 nightly Arduino IDE), and everything looks like going fine:

How to use a quadrature encoder

hi 

i have a Advanced Rover 5 Robot Platform with four shaft encoder (quadrature encoder)and im asking about if there is a libirary

arduino that makes me counts the number of revoultions and check if it is forword or reverse , if not is there eny reffrencies that

gives me information of how to code it what type of out and hot to change this output for my desired specific case 

***note that ***

the picture of the shaft is below and also the rover data sheet 

 

thanks in advance

Arduino motor control problems!

 

Update 06/11/2016

Hey guys,

I sort of got the motor working. Adding a small resistance(about 2-3ohms) in series with the motor seemed to stop the Atmega reseting whenever Pin 3 was pulled HIGH (still don't know for sure what was causing this!). I'll still continue t troubleshoot this problem and completely figure out what exaclty was causing the Atmega to reset, since the resistor is not a permanent solution (wasteful energy loss). I'm really grateful for the huge amount of help from here guys!! Thanks alot! :)

Cheers!

Arduino motor control problems!

Hey guys,

I'm having trouble regarding motor control in a project I'm working on.

It uses an ATMega328 DIP package on a PCB. The motors I'm using are small coreless motors and I'm trying to control them using Si2302ds N-MOS FETs. For the power supply I'm using a 3.7V(4.2V on full charge) Lipo. I've tested this setup on a promini before and the motors turned on and off just fine.
