LM358 Pulse Generator Module with Adjustable Square Wave Pulse

The LM358 Pulse Generator Module is a versatile tool designed to produce square wave pulses with varying frequencies and amplitudes. It allows you to modify the duty cycle and frequency by manipulating the trimpots located on the left and right, respectively.
By rotating the left trimpot in a clockwise direction, you can alter the duty cycle. Similarly, the frequency can be increased by turning the right trimpot clockwise. The module also features four jumpers to select the frequency, providing a range of options for different applications.

Frequency Selection Using Jumpers

• No jumpers: 0.3s
• One jumper: 4s
• Two jumpers: 7s
• Three jumpers: 10s
• Four jumpers: 15s
