Thanks for the help. It looks as though the shield is effecting the capacitance or resistance upon the power on reset. Adding the capacitor keeps the Reset pin active low long enough to complete the proper reset.

2  Using Arduino / Project Guidance / Reset Pulse coming to fase on: April 26, 2012, 04:36:49 am
I recently had a problem with my Arduino board where someone had suggested that the reset pulse was coming too fast. To avoid this I added a 0.iuf capacitor as instructed to the ground and reset pin to delay the reset. This worked.
My problem is understanding how the reset process works and how it affects the board. Could anyone explain this process to me as I cannot find it on the arduino website or any where else??

That has done the trick. Thanks for all your help.

Sorry about the two threads, I'm new to this. The Arduino does not have power when the switch is off! I take it to be a power issue if someone is suggesting using more batteries, but I do not wish to do this. Is there any other suggestions??

Hi, can anyone help me with this.
I've created an Arduino uno shield that has a serial LCD, Piezo Buzzer, Shiftbrite and a Xbee connected to it. It is running off a 9V battery that I have connected to the Arduino. I use a switch to turn the battery on and off. The problem is this, every time I turn the power on, the sketch that I had previously programmed on the arduino won't load up unless I physically press the reset button. Is there a reason why this happens and can anyone suggest some solutions so I do not have to keep pressing the reset???

Hi, Can anyone help me with this.
I have created a shield for the arduino uno that has a Serial LCD, Piezo Buzzer, Shiftbrite and a Xbee connnected to it. It's running off a 9V battery that I have connected an on/off switch to. The problem is that when I turn the power on, the Arduino sketch that I had previously uploaded to the board will not activate unless I physically press the reset pin on the Arduino. I don't want to have to keep pressing this when I turn it on. Does anyone have any suggestions as to why this is so and how to fix it????
