Fig. 2: Circuit diagram of Arduino based square wave generator. The 4×3 matrix keyboard is used as input device. The four rows (RW1 through RW4) of the keyboard are connected to digital pins 10, 11, ...

Circuit diagram of the RGB colour code generator is shown in Fig. 1. It is built around Arduino Uno board (Board1), 16×2 LCD (LCD1), RGB LED (RGB1) and a few other components. Fig. 1: Circuit of the ...

We are going to program the UNO to provide a PWM signal of different duty ratio for each of buttons. So we have a tone generator at hand which generates a different tone with each button press.

Circuit Diagram. The complete circuit diagram this Arduino Function Generator is shown below. As you can see we have an Arduino Nano which acts as the brain of our project and an 16x2 LCD to display ...

Makers, Arduino and electronics enthusiasts that have wanted to create a laser sky effect generator, may be interested in this new DIY tutorial which is being published by YouTuber “Normal ...

Provided is a downloadable “clean” sketch (Ardu_Sinewave.ino) for the sine wave generator, which is, in fact, an adapation of the wonderful work by Ken Boak and Trystan Lea.To test this, just attach a ...

The finished product was able to ring a modern electronic telephone, but it wasn't able to drive the physical clapper on an older phone. I didn't pursue it any further from that point, so take what's ...

A quick strong DIY output buffer for an Arduino (or other) pulse generator? I am not sure why pulse generator buffers are so fascinating at the moment. It could be that the workshop’s only ...
