Wiring Diagram Automatic Wiper Control using NE555

RealAutoTips. - One important part for our cars is Wiper. With Wiper we will easily clean our car glass when dirty or rainy. So we must very thank to wiper technology discoverer that used in our car now. We also must now that beside mechanic part in wiper, we also will find that in wiper any electronic circuit that used to control wiper run.

In this time we will show you very simple wiring diagram or electronic circuit schematic of wiper control automatically with few components and based on IC NE555 that easy to get in electronic market this time. Please see in figure 1 below to know more automatic wiper control circuit using NE555.

Wiring Diagram

Figure 1. Automatic Wiper Control Wiring Diagram (Circuitstoday)

Component List
  1. R1 = 47K
  2. R2 = 500K
  3. R3 = 100K
  4. R4 = 1K
  5. R5 = 47
  6. C1 = 25 uF/16V
  7. C2 = 0.01 uF
  8. C3 = 100 uF/ 16V
  9. Q1 = 2N6107
  10. Q2 = 2N3055
  11. IC1 = NE555
  12. M1 = Wiper Motor

Description 

Wiring diagram of Automatic Wiper Control using NE555 like in figure 1 above. According Circuitstoday site describe this circuit that a continuously working wiper is a big problem when it is raining slightly.The wiper control given here makes the wiper to sweep at rates from 1S to 10 S. The circuit is build around an a-stable multivibrator using NE 555.

Here the output at pin 3 remains high for a time period set by R2 ,and low for a time period set by R3.The low output pulse drives the transistor pair to drive the wiper motor to make one sweeping cycle and waits for next low pulse to arrive for next sweep.The high going pulse at pin 3 determines how many time should wiper should sweep in a given period of time.
