Any guidance?
Have you soldered wires to the IRtemp?

Re: Sketches are lost on power down, boot loader issue?

The quickest fix is to reflash the bootloader.
You can use your Mega as a programmer.

Re: Automatic MAC address

Can you check that the jumpers on the rear of your EtherMega PCB haven't been cut? If so, re-solder them.

Re: Adding tones to Cube Invaders

If you want the tone after the player moves, try your tone function at the end of the void updatePlayerPosition() function.

Re: Coding for light sensor project

Try the following sketch. When the light level is below 10 the LED turns on for five seconds then turns off. // Define analogue pin int sensorPin = 0; int lightPin = 2; // Variables int lightState = 0; int lowThreshold = 10; int highTreshold = 40; // Setup void setup() { // Init serial Serial.begin(...

Re: Usage of DMD2 with Ethernet shield

You can use different pins for the DMD by using the SoftDMD function in the DMD library. You will need to manually run wires from the DMD cable to the board however this eliminates the Ethernet conflict.

Re: MAX Number of DMD

To run 20 ... falls outside the scope of the display ecosystem with Arduino/AVR/SAM etc.
You would really want fewer number of large panels and a dedicated control board - a more commercial situation.

Re: Ethermega stops

If the different IP is working then go with that, I can't see why .30 would give you problems.

Re: my cube stopped working :(

You may have overfilled the buffer - there is only 2.5k SRAM to work with in total for the Cube.
