Sometimes you don't need a large microcontroller to get your work done. In this installment, TK teaches us how to use the ATtiny combined with Arduino to use the PWM function found on this chip.

PWM pins work the same way across all Arduino boards, so you don't need to go out of your way to buy a Mega if you already have a board supporting PWM. On the Uno, Nano, and Mini, the PWM pins are ...

Most projects are built on abstractions. After all, few of us can create our own wire, our own transistors, or our own integrated circuits. A few months ago, [Julian Ilett] found a problem using th… ...

Here is an Arduino based circuit with three independent pulse width modulated (PWM) channels to fulfil your requirements! Just follow the schematic diagram to complete the construction, and use any ...

Universal (ish) Arduino grbl opto-coupler interface also works with logic-level pwm In adding an alternative cutter drive motor (‘spindle’) to an existing cnc machine, an electrically isolated pwm to ...

Community collaboration is a great thing. Take the Arduino PWM library for shift registers. Some folks at the Arduino forum pitched in and helped [Elco] trim off a bunch of clock cycles by using ...

– More PWM channels: For Motors, Robotics, Actuators and more! – More ADC channels: Monitor more sensors! – A second SPI bus: Simplify wiring – More GPIO: for when your running short on pins ...

If you've got an Arduino of any variety, you might have noticed some of the pins on the board have a tilde mark or PWM printed next to them. What is PWM?

In adding an alternative cutter drive motor (‘spindle’) to an existing cnc machine, an electrically isolated pwm to analogue converter is needed. The machine uses a ‘grbl’ controller, which has an ...
