Cut it, strip the wires and hook in the battery and resistor as shown. (Most cheap phone cords contain only two wires, but if the one you buy happens to have four, then use the center two.) When two people pick up the phones together, they can talk to each other just fine. This...
allows you to use RX as a general purpose input (or another output), while still writing debug messages to Serial. Again the 330 ohm resistor in the RX lead to the Flash programmer protects against shorting out the programmer's driver. NOTE: S1 will have to be open in order to program ...
Step 3:To discharge the capacitor, use a 20,000-ohm, 2-watt resistor -- an inexpensive wire unit available at most electrical supply stores. Fasten the probes of the resistor to the terminals of the capacitor; this discharges the capacitor. If the capacitor has three terminal posts, connect...

Are you waking the device by wakeup pin? If so, have you set the pull up/down resistors? In an early attempt I had set my system up for wakeup via pin but did not set a pull resistor and the behavior was, as you would expect, unpredictable. ...
What you have created is a simple bulb thermometer. And it works pretty well. If you wanted to you could calibrate it, and it would tell you the temperature fairly accurately. This particular thermometer has a few problems, however: Because the working fluid is water, it cannot measure tempe...
1. Ensure commands refer to correct I2C addresses by checking the IDX pin. a. The IDX pin configures the control interface to one of many possible device addresses used in I2C communication. Usually for 1.8-V or 3.3-V referenced I2C I/O voltage, a pullup resistor and a pulldown resistor...
