and use the “analogWrite” command to control the duty cycle, as shown in the below experimental sketch prepared for Arduino and ATtiny85: int PWM_pin = 9; // LED pin for Arduino Uno (D9) //int PWM_pin ...

Planning another Arduino build? If you’re just doing something simple like switching a relay or powering a LED, you might want to think about the Digispark. It’s a very small ATtiny-based ...

Whenever a valid key is swiped, the Arduino triggers a relay which can then be used to control just about anything. In this case, [Jason] plans to use it to control his garage door. The system ...

Being new to Arduino, but having one project under my belt, I though I would try another. I wanted to play with a high-speed PWM – of which the 8pin ATtiny85 (or ..25 or ..45 – different flash only) ...

The tiny Nanite 85 Arduino development board was created as a fun project after its creator Tim had seen the Digispark and, subsequentally, the Adafruit Trinket were announced.
