Child sleep clock

An electronic device, comprising:

• a body shaped like a robot including a face, a torso, and two legs;
• five light emitting diodes (LEDs), wherein two of the LEDs are disposed in the face and three LEDs are disposed in the torso;
• a digital clock face disposed in the torso;
• a printed circuit board (PCB);
• and
• circuitry configured to perform sleep training, wherein the circuitry for performing sleep training is configured to:
• display a time on the digital clock face,
• determine whether the electronic device is in a wake state based on the time,
• based on the determination that the electronic device is in the wake state, turn on the two LEDs disposed in the face and turn off the three LEDs disposed in the torso,
• determine whether the electronic device is in a sleep state based on the time, and
• based on the determination that the electronic device is in the sleep state, turn off the two LEDs disposed in the face and turn on the three LEDs disposed in the torso,
• wherein the PCB includes a programming port configured to allow a temporary physical connection to be made between the PCB, including components mounted on the PCB, and an external computer,
• wherein the programming port is configured to receive a probe device that mates with the programming port, wherein the probe device includes a PCB to which six pins are attached to make temporary contact with corresponding locations on the programming port, and
• wherein the programming port is configured to receive three non-conducting pegs of larger diameter attached to the probe device that fit into corresponding holes in the programming port, wherein the six pins and three pegs are arranged in a 3×3 pattern with the pegs taking positions that only allow the probe to mate with the programming port from one side of the board and in one direction.
