The Temperamental Robot Learn to Solder Kit features a fun robot with attitude that comes to life when it gets hot. Just grasp the Temperamental Robot's heat sensor with your fingers. If you are "hot blooded" within a second or two 3 bright LEDs will light up, one will flash and the Robot will spin around. Temperamental Robot will cool down, then shut down after a few seconds and will wait for the next person to activate it. If you are "cold blooded", you can grasp the Robot's sensor and nothing will happen! The kit features about 20 components you install to learn good soldering techniques. Once you have mastered soldering, you then install the working electronic circuitry components. Operates from one 9V battery (not included). Size of PC board is 1.5" x 3.5".
