One 1381 part (CMOS voltage-controlled trigger available at different limits) Get one that matches the voltage across your motor (2V in this case) 8. The other terminal of the motor is connected to the 3300uf capacitor which is in turn connected to the other terminal of the solar panels. (The diagram shows 4700uf. Don`t worry. As you will see later, the values can be altered to get different

effects for the robot. ) Ans: This project will help you develop the confidence on many future electronic projects. Do not worry if you don`t get it right the first time. The connections are simple but they may get confusing for the first timer. So make atleast two or three attempts before giving up. If you make those attempts, you surely will not have to give up is our belief. Ans: The diode can actually be discarded. The diode is actually added to prevent the battery discharge through the solar panel. Since we are not using a battery and the circuit does not need the capacitor to retain charge when the panel is not in the light, the diode becomes superfluous. But as we said, this is based on the Miller solar engine and so the circuit diagram shows the diode. If you are using one, any diode will do. The specifications are not important. 2. Vary the resistor and capacitors to find the optimum solution for your robot. This will alter the power going to the motor ( and hence the intensity of the robot movements) and the time interval between the movements. The solar energy is stored by charging the capacitor in circuit and when a threshold level is reached, the 1381 part gets triggered and works the motor. 4. The values of the small capacitor determine the burst` of activities. Larger the values, longer will be the dance but intervals between will also be longer and vice versa.
