The goal of this hands-on-discussion is to walk away with a robot vehicle controlled by your Netduino. We’ll design and assemble the hardware then program the Netduino to move your robot around the room. We’ll look at controlling DC motors using your Netduino and discuss how to isolate the motor to prevent damaging your micro-controller. Finally, we’ll connect and program the L293D Motor Driver to control the speed and direction of your vehicles.
In Part 2 we’ll look at adding a sonar sensor to detect and avoid obstacles.
Parts you’ll need:
- 2WD Chassis $20
- L293 motor Driver $2.50 Can also use the SN754410 pin compatible chip
- Breadboard & jumper wires $6.50 (also at Radio Shack)
- 9v Battery Cable $1.92 (also at Radio Shack)
1x 9v battery (recommend bringing additional batteries)
Bring your Netduino 1 or 2 ( Netduino Plus will work but draws more power )
