Projects using the ATtiny10 Microcontroller IC - LED Dimmer Controller
[Issue 55] "Ultra" Tiny
Programming. We take a close look at the ATtiny10, the smallest
microcontroller produced by Atmel, and how
makers can use it to make compact projects.
There are a number of projects online featuring the
ATtiny10, however, we've noticed, in particular, many don't
pay attention to the rather complex nature of register
programming and logic - a process that's required to use
the ATtiny10. To break it all down, we've built a few projects
to show you how to get started and understand a different
paradigm in Arduino programming.
In this example project demonstrated here, we build a PWM generator. PWM (Pulse-Width Modulation)
can be used to dim LEDs and other resistive loads efficiently,
so it’s a good task for a compact microcontroller like this.
Handily enough, this project can be made into a waveform
generator by changing just one line of code. Leaving it in
PWM mode creates a fixed-frequency, variable duty cycle signal, while switching it to the waveform mode inverts this
behaviour. In other words, a square wave signal with variable
frequency.
