I have built a remote control car, pwm speed controll and all, using picaxe microcontrollers and gained a lot of experience doing it.
I used a low power i think 20mw transmitter you can find all over ebay that uses a 433hz carrier wave. A long time ago i found a 1w transmitter meant to be a step...
I would like to know is there a monthly limit for a single user for "good " questions in Homework sections ?
What is the daily limitation ? Are "small" math question also required to be asked in "homework" section ?
Thabk you and best regards
