Controlling RGB LED using PICAXE-08: Basics of software PWM
I’m working on a new RTFMs episode that involves packing an RGB LED and a microcontroller into a very tight space. The microcontroller I decided to use is PICAXE-08. I chose it for three reasons:
– I had one in the box
– I had no other plans for it as it…
Reading ATtiny85/45/25 Internal Temperature Sensor
I am working on one of my projects from RTFMs video blog (check out http://rtfms.com) that requires temperature sensing in a very small packaging. Naturally my choice is ATtiny85 – an awesome little chip from AVR that besides other goods (like 6ch PWM, serial interface etc) has internal temperature…
Choosing best high-end HT (amateur radio handheld transceiver)
Here is some information for those looking for a high-end HT. My requirements are:
At least dual-band (tri,quad-band is a plus), including 144 and 440 bands at minimum
Good wideband receiver
All-mode receiver
Convenient control
Weather proof
Ruggedly built
Having a lot of features, leaving a lot of space for experimentation
