I have used IRL640PBF mosfets to drive fair size motors with an arduino. These are logic level drive devices. Take a look at the gate threshold voltage in the datasheet, this gives a good clue to their suitability for low voltage use.
I need to connect eight 5 Volt ttl serial rfid readers onto the tx/rx pins. Has anybody got any examples of this being done? or any suggestions for suitable chips to make the job as simple as possible.
I think my less than 1 week memory span is causing me to post garbage again.
If the watchdog times out, it resets the chip with the watchdog timer set to a fast reset time, this is what causes the problem with the watchdog/bootloader looping continuously, and making reprogramming the chip all but impossible.
However, if the chip is powered down and restarted, the bootloader does operate correctly because the watchdog has not yet been enabled in setup().
If you can get a thin screwdriver under the ends of the plastic part of the header and gently lever it up it will come off easily and leave all the pins still soldered in the board. The broken off pin can then be removed easily. Replace the plastic and everything is as good as new.
