Walking Robot DIY Kit NE555 Educational Training Part<br>Instruction:http:\/\/img.banggood.com\/file\/products\/20160128025614SKU273253 Instruction.doc<br>Introduce:<br>1， The robot is the result of scientific and technological progress of the new development of educational robot Kit， it has circuit streamlined， practical， strong learning and still have strong interest and so on， are parts of an entertainment teaching in music teaching.2， Assemble the robot can move forward， backward， sound， flashing eyes and other movements.3， Adjust the circuit elements (potentiometers) can control the robot walking time and distance.<br>Simple principle:<br>This time base circuit block of integrated circuit NE555， internal， such as comparators， RS trigger， discharge tube parts， Figure 6 foot r end of positive input and discharge end together 7 feet do prepare for RS flip-flop flip. 2 feet is the inverting input of the s end-end， 3 pin is the output. RS triggers when the initial state of the Q output low level cut-off does not discharge the discharge tube， 3 pin output high. W2， R13， C5 is steady at this time delay circuit， power C5 charge through W2， R13 (W2 C5 can be adjusted up to trigger time) when the C5 voltage of 2\/3VCC is reached， r-end flips the output high. S-end level basically unchanged to RS trigger to flip into another， Q output a high level， the discharge tube pass C5 voltage transient was pulled for low level. For in are steady-state Shi MT2 end for high level on C1 full has electric， 2 feet has been in high level， dang RS triggers triggered flip into another steady-state Hou MT2 into low level， at C1 through W1， and R6， and R14 on to discharge， regulation W1 can regulation discharge of time， dang C1 end of voltage down to 1\/3VCC Shi s end compared device flip led RS triggers into are steady-state， followed by cycle， respectively regulation W2， and W1 can control are， and negative steady-state circuit of delay length. Pin 3 is steady-state output of positive and negative， positive and negative steady-state output of positive and negative， respectively. The level added to the capacitor C2 C2 charging output levels steady， the signal level is behind the driver's control. The control signal by R5 added to 9013 of base very， 9013 is NPN tube， base very positive usually 9013 of c， and e very guide pass， and 9012 as， also that is are steady-state Shi 9013 guide pass， 9，013 set electrode was pulled for low level， again after R7 added to VT3-VT2 of base very VT3 guide pass， to VT5， and VT7 guide pass， current through MT2 after motor Hou flows through MT1. Motor is turning the robot walks forward， voice and flashing eyes. W2 controlled motor Turning time. When the 555 in the steady-state output low， R4 add to VT2， VT2， VT4， VT6， VT8 conducting. Current by MT1 Motors through MT2. Motor reverse robot back vocal， flashing light circuit power through a diode， forward with voltage， reverse diode by voice circuit no voltage， flashing lights stopped working.<br>No
