ABSTRACT:
A programmable electronic circuit is disclosed. The circuit includes a CPU, signal-generating circuitry, and RC circuitry having at least two capacitors, such that when both of the capacitors are switched into the RC circuitry by the CPU, a signal is produced from an output of the signal-generating circuitry that is longer in duration than when one of the capacitors is switched into the RC circuitry.
