At a minimum, there will be two encoders. I got an old PS2 wheel mouse, from a garage sale for. Inside were two fairly high resolution encoder wheels, two sets. IR emitters, two IR detectors, three micro switches and another simpler. At first, I was just going to de solder the IR components from the. However, when I looked up the chip that ran the mouse, it turns out. The chip debounces the switches, decodes the. X and Y axes. It also turns out that PS2 mice are. TTL voltage, low current demands, flexible. Why the heck would you throw all that. So I wrote this sketch to get my arduino to talk to the mouse. There are NO external components needed you can wire the mouse. A PS2 connector has 6 pins. One is ground, one is power. The other 2 are not connected. Not connected. Not connected. Above numbers refer to this scheme, showing a female PS2 jack. Plug the power pin into the 5 header pin, the ground to ground. Then connect the data and clock pins to two of the arduino digital pins. The sketch uses pins 5 DATA and 6 CLOCK. Note If you want to put a PS2 connector on your board you will be likely to find one in an electronics store labeled as female 6 pin Mini DIN connector. Youll need to look on line for detail of the PS2 protocol. The status byte contains the. X and Y values, and also the button states. Attach mouse. txt. This modification to mouse.

I had to experiment a bit to find the right connections, though, so heres a photo to help others. You can measure from the pins on the connector to the wires inside the mouse. Note which is which before you cut the cable. These wires are most likely colour coded, like mine visible just left of the captions. Emulating a PS2 device. The ps2 protocol is not symmetric. Acting as a device is different from acting as a host. The attached library, ps. It can be used to act as a mouse or a keyboard. Attach ps. 2dev. Arduino Masterclass Part 4 Build a mini robot. Meet Rolly our first autonomous microbot based on an Arduino Uno microcontroller and our own special sauce software. The Arduino Uno might be an aging 8 bit microcontroller board but when it comes to interacting with the outside world its much easier to use than an Intel Core or AMD FX CPU. The Unos cache of analogue and digital inputs and outputs are perfect for many real world tasks and so far in this series thats what weve been doing lighting LEDs using temperaturehumidity sensors and even creating a simple composite TV output. However this time were ramping things up pulling in parts from e. Bay Bunnings Jaycar and the local 2 shop to create a microcontroller powered robot microbot called Rolly. This isnt a remote controlled bot Rolly thinks for himself avoiding obstacles and determining his own direction. Well be looking at how to build Rolly in a two part project introducing lots of new components and features looking at some new theory and as weve done in this series showing you how to put it all into practice. Getting the parts. The first thing youll want to do is get the parts together. The goal in designing Rolly was to make a robot that was as cheap as possible to build and run yet still capable of showing personality. Depending on how many of the parts you have already the cost can come down to as little as 4. See the table below for the detailed parts list. Just be prepared you may need to wait a few weeks for those e. Bay parts to arrive. We havent included other items such as a soldering iron yes theres some soldering required needle nose pliers miniature flat blade screwdriver and the like so well leave that for you to sort out check out our Tech Corner on Soldering 1.

Project 4 Mini Robot. The source code also contains the library files needed to run the external devices. Block diagram. Well talk more about how Rolly does what he does in the next series but the block diagram will give you a good idea of whats going on. The microbot combines a number of real world devices that were controlling all at the same time. It starts with the Motor Drive Shield shield is the Arduino name for expansion boards to provide extra grunt to handle the two DC traction motors plus the neck servo motor on which the ultrasonic sensor eyes sit.

The ultrasonic sensor provides accurate distance information down to the nearest centimetre and its used to determine whether Rolly needs to stop and back up or simply veer away from the object blocking his path. Although its connected to the Motor Drive Shield data from the ultrasonic sensor feeds directly into the Arduino microcontroller board. Steering the microbot is as simple as controlling the spin direction of the DC traction motors if the left motor drives forward and the right motor backwards the bot will turn right and vice versa. With both motors driving forward the bot will obviously move forward and vice versa. Its all controlled via the source code. But thats enough of the theory lets start building Step 1 The base. Yes were using the lid of the food container as the base for our microbot. If youre sniggering stop it you can build yours out of whatever you want. Just make sure its approximately 1. You may need to cut away a flange at the edge on either side of the lid to allow the shaft of the motor wheel to move freely. Carefully use a box knife and make sure you have all your fingers afterwards. Next drill two holes diagonally for the caster wheel at the opposite end of the base to your flange cuts. Use the caster wheel mount plate as a template mark the holes and drill them. Tip When drilling into plastic set your drill to the lowest speed start with a 2mm drill bit and work up to a 4mm bit. If you drill at high speed all at once youll rip the plastic to shreds. Yes that really is a food container lid as our base its cheap and see through. Step 2 Solder the capacitors wires. The 0. 1u. F capacitors have to be soldered across the motor connections and help reduce electrical noise in the circuit otherwise the Arduino gets a bit cranky. Provided you use ceramic or Mylar capacitors they have no polarity so just solder one leg to each motor connection tag and do so on both motors. Try to lay the capacitors flat against the yellow gearbox body to keep things neat. You also need to solder onto the connection tags the wires that go to the Motor Drive Shield. Try attaching them to the capacitor leads if youre not confident to get everything soldered at the motor connection points. These motors have a D shaft and wheels that simply press onto the shaft. Use just enough pressure to get the wheel on. After that cut a small strip of double sided padded tape peel back one layer and press it against the motor gearbox which will mate with the base. Tip The motor connection tabs are quite weak so dont bend or force them. And take no more than five seconds to solder the capacitors or you might cause the motor connection to break. The 0. 1u. F capacitors help reduce RF noise on the supply rail. Step 3 Install the DC motors. Install the two DC motors to opposite sides of the base using the double sided tape. Get the motors as close to the edge as possible to allow the wheel free movement. Use double sided padded tape to attach the motors to the base. Step 4 Add the horn to the motor. The little SG9. 0 servo motor gives our microbot a neck so it can spin the ultrasonic sensor on its axis. The servo motor itself should come with an accessory pack of attachments called horns. Use the two sided arm and press it onto the servo motor shaft. Youll probably need to use a bit of force to get it on the first time but try not to use too much. Use the two sided horn on the servo motor. Step 5 Solder the wires to the shield. The Motor Drive Shield provides the extra drive power to control the DC motors. It also provides connection for the servo motor and the ultrasonic sensor for which youll need four male to female Du. Pont wires. If you bought a bag of 4. Motor Drive Shield. Solder one wire to the 5. V rail one to the GND pin and one each to analogue pins A4 and A5 down in the bottom right hand corner. Check the block diagram for pin assignments. Solder four male to female Du. Pont wires to the Motor Drive Shield. Step 6 Add the shield to the Arduino. The Motor Drive Shield has a series of pin headers on the bottom of the board these align with the headers on the top of the Arduino.
