Unfortunately, the AD9833 doesn’t have a way to control amplitude, something which is pretty important in a function generator. So [Faransky] uses a X9C104P 100KOhm 8-bit digital potentiometer ...

We set the potentiometer pin as 0 (A0 on the Arduino Uno board), the CONTROL variable is the voltage that is used to cotrol the led brightness of the speed of the fan. In the setup() function the ...

Features of the DIY function generator Arduino project include: – Fully digital control: No need for passive analog components, which simplifies the design and enhances reliability.

Sometimes, a hack isn’t really about the technology but about the logistics. If we asked you to light up an LED using an Arduino, there’s a good chance you’d know exactly how to d… ...

The Arduino Mega's PWM pins are digital output pins located on D2 to D13 and D44 to D46, coming to a total of 15. While they function as normal digital pins that can switch a component either ...

This means that I can measure the resistance and get the angle by using the following function: Simple enough. Hopefully, it will be useful also (to me). If you have your own potentiometer, ...
