Arduino Pulse Generator Frequency Sweep

 In this tutorial we will learn how to make a Pulse Generator with a Frequency Sweep. Pulse generator will start with 1Hz and increase its frequency for 0.5Hz every second. Once it reaches 10Hz it wil stop increasing the frequency. You can set your own Starting frequency, End frequency, Frequency increment, and the increment interval. Step 1: What …

How to Use Arduino DDS Frequency Signal Generator AD9850

In this Tutorial we will learn how to make a Frequency Signal Generator using a AD9850 module and Arduino. Watch the Video! Note: I managed to get frequency up to +50MHz but the signal quality gets worse with the higher frequencies. Step 1: What You Will Need Arduino Uno or any other Arduino board AD9850 …

Simple Frequency Counter Using Arduino

In this tutorial we will learn how to make a simple Frequency Counter using Arduino. Watch the video! OLED LCD Display Jumper wires Some sort of frequency generator, it can be another Arduino but in our case we will use a cheap 555 module. Arduino Uno or any other Arduino board Visuino software: Download here Step …

Arduino Mosquito Repellent

In this tutorial we will learn how to make a simple mosquito repellent using arduino and a piezo buzzer. The buzzer will emit the silent (to human ear) frequency of 31kHz, this frequency is known to repell the mosquitoes and you can adjust the frequency to your needs as well. Watch the video! Step 1: …
