Question 1

As a volunteer for Public Invention, I have developed an Atmega328 based design in which I thought I was largely duplicating the Arduino UNO. Unlike the UNO, I did choose a CH340 USB to UART chip as ...

Question 2

I have been working with my Arduino UNO for 2-3 hours and after that it was not possible to load sketchs into the board since it returns a "avrdude: stk500_recv(): programmer is not responding" ...

Question 3

Similar to Will the Uno bootloader work in the Duemilanove? but the other way around. I have an Arduino Uno. I require a slower upload speed than the 115200 baud rate used in the Uno's Optiboot ...

Question 4

I have a duemilanove which originally had a 168. I have some ATMEGA328 P chips and I've put one into the duemilanove. I am using a Uno as a programmer for the duemilanove. I am running Arduino 1.8....

Question 5

I am unable to access elements of a 2D PROGMEM array from inside a loop. Please see the following example: const byte a1[] PROGMEM = {'a', 'b', 'c', 'd'}; const byte a2[] PROGMEM = {'e', 'f', 'g', 'h'...

Question 6

I want to control 4 (or more) LEDs using the PWM output pins of my Arduino. Here is how I have it on a breadboard, and it's working for me. Question: Is this schematic inefficient? Are there any ...

Question 7

I recently saw this video where the creator controlled a DMX light via the Arduino. There he used the pins 3 and 4 for the data on the Arduino Duemilanove. As DMX library he used DmxSimple. Based on ...

Question 8

I made a vibration sensor using an Arduino. It is connected to an Android app. When the start button is pressed on the app, a red light LED turns on (stand by), and after 2 - 5 seconds, the red LED ...

Question 9

I'm trying to connect 2 potentiometer (10k) and pass their value to Hairless Midi software (For Serial to Midi Bridge) the first pot is working fine but the second pot's value keep on changing and ...

Question 10

So what exactly I am trying to do is control a motor and be able to turn it both ways without any extra parts. So if the hmp was on (the plus pole) and the hmm (the minus pole) acted like ground the ...

Question 11

Good morning, I would like to use an Arduino Duemilanove to read the voltage signal generated from a current sensor (CSLA2CD). The datasheet for this sensor can be found here. The problem is that ...

Question 12

avrdude: stk500_getsyn(): not in sync_resp=0*00 avrdude: stk500_disable: protocol error, expect=0*14,resp=0*51 These are the errors occurring when I am trying to upload to the board. I've tried all ...

Question 13

I am designing 8*8 reed switch matrix which will be connected to Arduino. I am using Arduino Duemilanove. I have completed the matrix portion but don't know how to connect and where to connect the ...

Question 14

I've got project that needed to have some (4) digits display, and had plenty of 7 seg. displays lying around. I didn't have any multiplexers left but have instead wired it up as per this diagram: I've ...

Question 15

I need four Fast PWM signals for four different transistors. I want to use timers 1+2 (pins 3, 11, 9, 10) so it wouldn't interfere with delay(...). I tried setting the timers to Fast PWM mode, and ...
