Arduino Project Ideas - Part 12
Ping-Pong Ball Cannon
Grab some motors, some cardboard and hot glue and have fun!
2 x 13,000RPM 6V DC Motors
1 x 60V 10A NPN Power MOSFET
1 x 7.4V 1300mAh LiPo battery
1 x small servo
2 x 3D printed flywheels
2 x thick rubber bands (from broccoli bunches)
Lots of cardboard and hot glue
Some stiff wire for the servo actuator arm
Wood frame for holding motors
1 x Arduino nano and some code
The full project on arduino.cc
Meatball Shooting Gallery Game
Processing-based game based on the work of Kevin Darrah
Target projection feature, sound and 'Flying Meatballs' added by Gord Payne
micro:Bit School Bus
topAprNo need for an expensive kit!
Just grab a couple of geared motors, an inexpensive motor control chip and two micro:Bits and build a remote-control robot car!
Here are the full build instructions
April 23 Update - I added flashing lights and a swing-out STOP sign to the bot. This is not that much more challenging to code, but the fabrication is considerably more challenging than the original robot project.
