420 Servo Signal Tester

420 : Servo Signal Tester

Design render
  • Author: Holunder
  • Description: If you provide a 4kHz Clock and 8 LED's as Output, the LED's will light up according to the Servo Signal on Input 0
  • GitHub repository
  • View in Wokwi
  • Clock: 4000 Hz

How it works

If you apply a Servo Signal it will be processed via Flip-Flops so that the Servo Signal controls the Pin's on the Output. If the Servo Pulse is 1ms (0 degree) no LED will light up and if the Servo Pulse is 2ms (180 degrees) all the LED's will light up.

How to test

Add 8 LED's to the Output's and connect a Servo Signal to Input 0

External hardware

8 LED's and resistors. (If your LED's need more Output Power then the Chip can provide, use a driver) Maybe the resistors can have a low value, because the LED's are only ON when the Servo Signal is HIGH. So the maximum is 20% duty cicle.

How to use

Add 8 LED's to the Output's and connect a Servo Signal to Input 0
