Crush Cans Effortlessly with an Arduino Powered Arm. Photo by Hep Svadja. This project is excerpted from Make Action by Simon Monk, available at the Maker Shed and fine bookstores. Linear actuators convert the fast rotation of a DC motor into slow linear movement, and they can provide quite a strong pushing or pulling force. You can easily control these actuators using a simple H bridge circuit put it together with an Arduino and a bit of woodwork, and you can make yourself an automatic crusher for beverage cans  no soldering required H Bridges. An H bridge is a simple circuit that uses 4 switches to change the direction of a DC motor forward or reverse by simply reversing the polarity of the motors connections. With all 4 switches open, no current can flow through the motor. Top VIdeos. Warning Invalid argument supplied for foreach in srvusersserverpilotappsjujaitalypublicindex.

Stepper Motor Control Circuit L298' title='Stepper Motor Control Circuit L298' />However, if switches S1 and S4 are closed, but S2 and S3 are open as shown here, current will flow from the positive supply to terminal A of the motor, through the motor and S4 to the negative supply, and the motor will turn in one direction. If S1 and S4 are now opened and S3 and S2 closed, the positive supply will be applied to terminal B instead and flow out through the motor and S2 to reverse the direction of the motor. Interestingly, you can brake the motor by closing S1 and S3 simultaneously or S2 and S4. Just dont close S1 and S2 at the same time or S3 and S4 or youll cause a short circuit The L2. H bridge module contains 2 miniature H bridge circuits that work in exactly this way. CAUTION Linear actuators are strong. Driver Lexmark Z32 Windows Vista. This project is about crushing beverage cans, but the actuator will quite happily crush a hand or anything else that you put into the crushing area. So be careful, especially while youre getting it to work, when there is a temptation to adjust and intervene. Wire the circuit. Figure A illustrates the wiring diagram for the project, and Figure B shows a close up of the Arduino and H bridge module. Fig. AFig. B. Photo by Simon Monk. The L2. 93 module has jumper pins that by default keep its H bridge circuits enabled, and so only the two Arduino outputs connected to IN1 and IN2 are needed. Conveniently, the H bridge module includes a voltage regulator that provides a 5. V output that you can connect directly to the 5. V pin of the Arduino to supply it with power. Build the crusher. The basic structure of the crusher is a length of 24 wood. At one end, the actuator is anchored using the fixtures supplied with it. The actuators shaft is then fixed to a block of wood that crushes cans against an end stop. Two plywood sides help prevent the can escaping while its being crushed. I havent used exact dimensions, because your actuator is likely to be a little different in size than mine.

Remember to leave a bit of a gap between the fully extended crushing surface and the end stop otherwise, the machine might push itself apart. Program the Arduino.

Time period 3. 0 seconds for my motor sets how long the motor should be on, before reversing. The setup function controls the whole operation of the project. After setting both control pins to be outputs, it immediately starts the crushing action using the crush function. Be Nice to Your Motors. Imagine a car driving along and then suddenly being thrown into reverse gear thats pretty much what youre doing if you suddenly reverse the direction of a motor. For small motors without a great deal of mass attached to them, this isnt normally much of a problem. But you may find that if youre using a Raspberry Pi or Arduino board thats powered from the same power source as the motors, then the Pi may crash or the Arduino may reset. This happens as a result of the large current that flows when you suddenly switch directions, causing the boards power supply voltage to dip. For larger motors that are driving something with a lot of inertia, sudden changes in speed or direction can cause big problems. The resultant large currents may damage the H bridge, and theres also the mechanical shock to the bearings of the motor. This is something to bear in mind when designing control software for larger motors. One way to be nicer to your motors is to precede any change in direction by setting the control lines to let the motor stop, pausing for enough time for it to actually stop before setting it running again in the opposite direction. In Arduino, setting up this kind of delay function might look something like this forward2. In our can crusher code, you can see weve set full stops and also a delay of 1 second 1. Smash cans Push the Reset button on the Arduino to trigger the crushing action Figure C. Whenever the Arduino resets, it automatically starts to move the linear actuator. Smoosh Fig. CGoing Further. H bridges can be used to control other types of motors, including stepper motors. They can also be used to switch power to other devices, such as Peltier heating and cooling elements.
