My circuit with Arduino Due works perfectly with USB, when I plug a 9V battery on Power Jack works for some seconds then Arduino just turn off.
I tried with 3 new batteries and VIN PIN as well, is my board defective?
please check AMS 1117 ic..
first remove all connection and give 9 volt in input of ic.
After check voltage on output pin.
if output voltage is not equle to 3.3V,change ic.
your controller will work properly

I'm currently trying to burn the pinguino bootloader in a pic32mx250f128b which is 5V tolerant with an arduino uno. I'd want to try pic32 chips, but I haven't a pickit3 now, I can only access to pickit2.
So to burn the bootloader I'm using an arduino uno, and use the bitbang sketch from pic32prog to try to burn it.
For the wiring I did this :
All VDD and the VUSB3V3BUS pins are wired to the 3V3 regulator of the arduino uno.
All VSS pins are connected to the ground of the arduino uno.
Arduino D2 (PGC) is directly connected to PGEC1
Arduino D3 (PGD) is directly connected to PGED1
Arduino D4 (MCLR) is directly connected to MCLR
But actually, when I launch pic32prog I always have this output :
Programmer for Microchip PIC32 microcontrollers, Version 2.0.218
Copyright: (C) 2011-2015 Serge Vakulenko
(ascii ICSP coded by Robert Rozee)
Adapter: ... OK1 OK2 - ascii ICSP v1E
No target found.
I tried also with the couples PGEC2/PGED2 and PGEC3/PGED3.
I haven't tried to use a crystal yet, but I think from what I read it's not needed for ICSP programming.
For now here is what I've done on my breadboard :
photo of the pic on the breadboard
I don't know what could cause this detection problem,
Thank you very much for your help :)
Edit : I tried several things and here is where I am :
I added the pull-up on MCLR, capacitors on VDD pins, and others recommended : Still the error No target found.
I saw that pic32prog add compatibility with pickit2 so I tried it : this time the pic is detected but I get this error : Unknown CPUID : ffffffff. I tried also with a new pic32mx250 on the pickit2 to be sure it wasn't the first which was damaged.
Finally to recheck my connections I found another version of the datasheet. In this one it seems that PGECx and PGEDx pins aren't 5V compatible... -> So I'll test with 3.3v compatible circuit this time
you need 3k3 pullups to the 3v3 supply rail on both PGC and PGD. these two outputs are 'open collector' (simulated) and the 3k3 resistors define the logic '1' voltage fed to the PGC and PGD pins of the target PIC32.
as mentioned by others, you also need a 10k pullup on MCLR. in addition, you need to ensure that all Vcc pins (13 and 28) are connected together, all ground pins (8, 19 and 27) are connected together, and that there is a 10uF low ESR ceramic capacitor from pin 20 to ground (a 22uF tantalum will do).
see the "ascii ICSP construction guide" article here:
http://www.thebackshed.com/docregister/Browse.asp
the article includes a schematic of what is required.

the 10uF low ESR ceramic capacitor on pin 20 is crucial. pin 20 connects ONLY to this capacitor, nothing else. without it, the core of the PIC32 will not run and programming will be impossible.
the reason for this is that the core of the PIC32 runs at 1.8 volts, and the capacitor on pin 20 is part of the circuitry that generates this supply. in your photo it looks like pin 20 is not connected to anything.

Currently I am using a dip Atmega328p-pu with a breadboard built circuit. The problem is when i am supplying the circuit from Arduino Uno's 5V it is working perfectly fine, but it's not working when I supply it from power supply. When I mean not working, it has the typical blink code in it and it works perfectly fine with uno's 5v, but it keeps resetting or freezing in one part of code -the led just lights instead of blinking-
The circuit has 10k resistor in first pin, 16 mhz crystal, 2x22 pf capacitors near it and all power connections are also connected
Thank you
So, I'm building an Arduino toy car. It runs with 4 motors and has 2 color sensors and 8 IR sensors. It must work on battery because i don't want it to be hooked to USB all the time and motors require much more current than USB can provide. So here's the problem...
When I have my arduino powered with USB cable or USB cable and battery, it works perfectly, but when I have it powered only on battery (7.2V), 4 LED's in the left color sensor glow dimmer, and the right one doesn't even work.
I should point out that some of the pins of color sensor that should be plugged in 5V or GND are plugged in digital output pins set on HIGH or LOW.
The arduino i'm working on is Arduino Mega 2560 and color sensors are TCS230.
I think you should measure supply current of the board and then check if your battery is able to provide such value. Also try to feed the board from external supply through wall adapter connector (or Arduino's Vin terminal). The idea is that you may need higher voltage and(or) current, then 7,2V.
Check to make sure you have the correct resisters values in place to drive the LEDs. You can sometimes get away without doing so but it is iffy and you can sink a lot of current you don't really need to. I found this link, "Driving LEDs with an Arduino".
I am using a four relay shield to power solenoids, however every time a solenoid is used the Arduino reboots immediately.
We have done this for two different projects with the same type of shield and both cause the same problem.
I am having some trouble figuring out what is causing the system reboot. Any ideas?
The shield is the Catalex relay Shield.
It sounds like driving a relay coil is causing the voltage to drop. After the voltage recovers, the Arduino reboots like it was just turned on.
What happens when you disconnect the solenoids? Does the same behavior happen? These are relays, so the circuit on the relay side should be isolated.
Are you powering the Arduino from a power supply, or the USB port?
Oddly, if you look up the data sheet for the HLS8L-DC5V-S-C:
http://www.dipmicro.com/?datasheet=HLS8L.pdf
it says a 5V relay (L type) should have a coil resistance of 70 Ohms , for 0.35 W, so you should need 70 mA to drive it; I think there is a small transistor that drives that from the pins, but you still need the 70 mA from somewhere to close each relay.
Which version of the board do you have?
http://seeedstudio.com/wiki/Relay_Shield
My search on the Catalex Relay Shield pointed to the Seeedstudio version, but it could be that your board needs to be externally powered.
Is possible for Arduino to receive a 5V into a inputPin from a external battery?
If I have a system that has it's own power supply and after an event fires 5V. How can Arduino read this input?
This is an electrical problem, no software issue I presume.
Here is how to proceed:
1) Make sure both boards have the same ground (connect GND together and make sure there is no conflict)
2) Connect your output to an input on the Arduino board (pin 2 e.g.). This connection is preferably done using a resistor, 1 kOhm will be ok.
On software side, just set this pin as input pinMode(2,INPUT); in setup() and then get its value status = digitalRead(2); in loop().
