Automatic Wiper Control Circuit
Automatic Wiper Control
Description
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 astable 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.
Notes
Connect the circuit to 12V line from Vehicle and connect the wiper motor and wiper switch as shown in figure.
For setting the device first find out how much time it is required for the wiper to complete one sweep cycle.Now adjust R3 such that wiper makes correct one sweep cycle.Fix R2 some where on the dash board.And now the system is ready to use.
You can adjust the sweep rate of the wiper using R2 according to the intensity of rain.

This circuit is one of large wide use of 555 Ic
I like this circuit & it can be used for many applications
as example using light insted of motor
thank you
it is projected onto the wafer with intense ultraviolet light. The parts of the chip that are exposed to the light are then etched with gases and showered with ions to create transistors (see microprocessor). The transistors are connected when later cycles of the fabrication process lay down metal and insulation. Chip manufacturers fabricate chips in extremely clean environments because a single speck of dust can ruin the design of a chip that relies upon millions of microscopic electronic components.
I am a Sri Lankan who owns a 1980 Nissan Patrol 160. When I bought this 12 years ago most of the electric control modules were missing, including the wiper control module. I am interested in putting up this wiper control circuit published in your website. But my vehicle runs with 24 volts. Can anyone help me adjust the circuit to suit 24 volts? I greatly appreciate.
