Radio Controlled Lawnmower

admin — Mon, 25 Jul 2011 01:20:15 +0000

The project describes how to build a Radio Controlled lawnmower using Arduino, a cheap R/C transmitter and receiver pair, and a couple of electric-wheelchair motors. It uses Mosfet h-bridge (N-channel and P-channel Mosfets) to control motor speed.To implement the Failsafe, John David, the designer, used another Atmega168 (or an Arduino), to control a normally-open [...]

AVR Based R/C Pulse Generator

R/C Pulse Generator uses Microcontroller AVR AT90s2313 to measure resistance values and generate R/C style pulses that will be fit for driving servos or testing R/C controlled robots without the transmitter. It measures four channels and provides four R/C style pulses. Indication of the current pulse width and when the board is in CALIBRATE [...]

You can collect vital flight information about RC aircraft with this clever on-board telemetry module. The module sends information via a wireless ZigBee link to a ground station consisting of a laptop computer and a ZigBee receiver. The system is implemented using an MC1392 SARD board with a few modifications. A voltage follower built with [...]
