NE555 Square Wave Signal Generator
Duty Frequency Adjustment Pot DC 5V/15V 1Hz-200Hz
This is an NE555 square wave generator module.It has the function of producing a square wave signal that can be used in various applications. For example it is used in development boards, stepper motor driving applications etc.devices that operate with a square wave. It has 2 potentiometers for adjusting frequency and duty. The frequency can be adjusted between 1 Hz and 200 KHz. To increase it, the pots must be turned clockwise. The pots are multi-turn. They can be turned 30-40 turns.
There are 4 jumper selection switches on the board. With these switches 4 different frequency ranges are selected. You can examine the frequency ranges linked to the switches in the picture below.
Low Frequency: 1Hz to 50Hz
Intermediate Frequency: 50Hz to 1kHz
Medium Frequency: 1KHz to 10kHz
High Frequency:10kHz to 200kHz
When you change the duty setting the frequency will also shift. Do not forget this situation while using the board. The exact opposite happens too. A change in frequency changes the duty.
Period calculation formula:
Period T=0.7(RA+2RB)C
RA and RB Adjustable blue pots. 0-10K
C=100uF - Low frequency
C=1uF - Intermediate frequency
C=0.1uF - Medium frequency
C=0.001UF - High frequency
Features:
- IC: NE555
