Signal generator1/17/2024 Anyhow, you will not have any such issues as it is all sorted out, just follow the circuit carefully to know which pin is connect to what. Hence I had to mess up with the wiring a bit by changing the pin order. The connections which I used previously didn’t turn out to work dues to some reasons which we will discuss later in this article. The complete set-up is powered by the USB port of the Arduino itself. We also have a rotary encoder which will help us to set the frequency. As you can see we have an Arduino Nano which acts as the brain of our project and an 16x2 LCD to display the value of frequency that is currently being generated. The complete circuit diagram this Arduino Function Generator is shown below. Also what’s more fun than using a device, that we built on our own. But other than that it will come in handy for all hobby projects and you need not wait in weeks for the shipment to arrive. Do note that this generator is not of industrial grade and cannot be used for serious testing. Apart from that, the generator can also produce since wave with frequency control. This function generator a.k.a waveform generator can produce square wave (5V/0V) with frequency ranging from 1Hz to 2MHz, the frequency of the wave can be controlled by a knob and the duty cycle is hardcoded to 50% but it is easy to change that in the program as well. In this article we will learn how quickly and easily we can build our own Function generator using Arduino. While all of these can be purchased, we can also easily built few on our own like the Function Generator and the Dual mode power supply. A Multimeter, Clamp meter, Oscilloscope, LCR Meter, Function Generator, Dual mode power supply and an Auto transformer are the bare minimum equipments for a decent lab set-up. Every Engineer who loves to tinker with electronics at some point of time would want to have their own lab set-up.
