Generating 200kHz square waves for underwater communications I want to generate a square wave at 200kHz, and be able to switch it on and off The application is to drive an ultrasonic sounder in short bursts (ten or twenty cycles of 200kHz) as a way of transmitting data through water
Generating 200 kHz pulse on Arduino Uno in normal mode I need to obtain 200 kHz from Arduino Uno I am using Timer0 I have configured it to run in normal mode and the Prescaler is set to clk 8 (the clock frequency of Arduino is 16 MHz) TCNT
Simple Waveform Generator with Arduino Due With push buttons, you will be able to choose a waveform shape (sine, triangular, sawtooth, or square) that we will send to to send to the DAC0 and DAC1 channels and change the frequency of the generated signal with a potentiometer
