I wasn't happy with the way the square waves sound, so I explored using other methods of generating sound waves with Arduino.
The ESP32-BlueJammer (Bluetooth jammer, BLE jammer, WiFi jammer, RC jammer) disrupts various devices using an ESP32 and nRF24 modules (30m+)
In this Simple Tutorial we will learn how to make a PWM using Arduino and observe the Signal on the Oscilloscope.
Things you should know while amplifying a 10mv DC signal to 100mv or 1volt and different approaches to the configuration.
A simple TTL modulated diode laser.
Do you have a bunch of servos? What about a couple of big ol' motors, or even a ton of LEDs? You will probably need a capacitor pack.
A small, cheap, low-powered FM Radio Transmitter to create your own Radio Station at home.
In this tutorial we will learn how to use MCP4725 12Bit Digital to Analog Converter with Arduino to generate Square, Sine & Triangle waves.
