here are the schematics:



the power are coming from my cabin 12v solar battery bank.

Hi, I will post a schematic (just have to draw one first) measuring the pins I can't do until tomorrow my measurement instrument needs battery. Yes, I can't flash the Z-uno before it dies. To summon the connections, i had 6 inputs where I use ground for signal I had 4 relay outputs, and 6 led output...

Hi, I disconnected the z-uno, And wirhout any external connections it still heats up.

The flash is the only chip thats to hot to touch.

Hi I’m using 12v car battery

I removed the zuno from the bread board and I gets hot (burning) even on usb connection, about 30 sec.

I have not notis the problem beefore but until now I have only, been doing developments and it has not been on for more than a short time.

Have anyone experience the Flash chip 25pe40vp to become extremely hot?

after some seconds the chip gets burning hot and the z-uno stops working.

I fond the problem.
the long time=0; declaration should be unsigned long time = 0;

Now the switch are working as it should.

Thanks for looking at it anyway

If I make It smaller it works, Button 1-4 works but after 5 it does not. Before I posted the forum message, I tried to upgrade Arduino to 1.8.5 and installed the 2.1.1 Board. had the same trouble in Arduino 1.6.5 and FW 2.0.9 I have tried to rearange the pin setup for the buttons. If I increases the...

HELP! What am I doing wrong? button 1-4 works great, relay switches on as it should. but Button5 and 6 makes the relay flikker. turns on an off. #define Relay_PIN_1 9 //Relay 1 #define Relay_PIN_2 10 //Relay 2 #define Relay_PIN_3 11 //Relay 3 #define Relay_PIN_4 12 //Relay 4 #define Relay_PIN_5 13 /...

After upgrading to 2.1 I get the following error message

Z-Uno_Hytta_Alarm___:383: error: use of undeclared identifier 'SKETCH_FLAG_DEBUF'

uCxx returned error code:1

use of undeclared identifier 'SKETCH_FLAG_DEBUF'

I did not have this error with the previous version.

Her are an example, !not tested! #define Button_PIN_1 14 //Button 1 #define Button_PIN_2 15 //Button 2 #define SWITCH_ON 0xff #define SWITCH_OFF 0 //ZUNO_SETUP_DEBUG_MODE(DEBUG_ON); // Global variables to store data reported via getters byte LastButton_state1 = 0; //Button Last State byte LastButton...
