< Back Sound Detection Use the simple sound detector module to determine if there is sound above a pre-set threshold. In this exercise we use a simple on/off sound module to detect sounds. Use the simple sound detector module to determine if there is sound above a pre-set threshold. The threshold is set by using a small Philips screw driver to adjust the square blue variable resistor on the lower right side of the module. The output on the modules OUT pin is normally 5V when there is no sound. When a sound is detected it will drop to 0V and this is how the JackBord can detect sounds. Connect the sound sensor to Port A1, the Port A 5V supply and grounds of the JackBord as shown in the table below. Note the names of the pins on the detector module and the corresponding pins they connect to on the JackBord. When connected correctly it should look like this: Testing: With the module attached as above and the JackBord turned on enter the following command: btp a1 tg d1 When run this command treats the sound module as a button input. Each time the module detects a sound its output goes low, when there is no sound it goes high. Also the red led on the module will light up when it detects a sound. If the module does not seem to detect any sound try adjusting the blue variable resistor a little and try again. Or if it seems to be over sensitive to sound try adjusting the sensitivity down. Table of OUT values for the sound sensor module. Previous Next

< Back HC-SR505 Mini PIR Infrared Motion HC-SR505 is an infrared module which detects the movement of a person or animal, at distances of up to 3m. HC-SR505 is an infrared module which detects the movement of a person or animal, at distances of up to 3m. When it detects movement the output pin will go high to 3V. If, after the detection the object is no longer there, it's output will go back low after about 8 to 10 seconds. It uses an infrared sensor to detect movement in front of the sensor with a beam width of about 100 degrees. How the Sensor Works The output pin is normally low and will go high when a person or an animal crosses the sensors beam. This beam is like a 100deg wide fan centered along the axis of the sensor looking out from the white dome. Note: Once the sensor is triggered it will take about 8 to 10 seconds for it to reset once the beam is clear. Sensor Pins The pins of the sensor are shown below. Note this is the top view, you can check this by looking for the two yellow capacitors towards the bottom of this picture. The best wire color is included so you get into the habit of using consistent wires for the ground and power supply as this will save you a lot of trouble in the future. Connecting the Jumpers to the Sensor First we will connect the jumpers to the sensor. Then we will connect it to the JackBord. The sensor needs 5V to work. It needs 3 female to female jumper wires to connect to the JackBord as shown in the picture below. The output of the sensor can be connected to any of the pins on ports A, B or C. Parts Needed: You will need the following items: The sensor x3 female to female jumper wires, 10cm or more Connection Steps: Follow these steps to avoid damage to the JackBord or the sensor. The jumper wires are connected to the sensor as shown in the picture, note in our case we have used a red jumper for the 5V power, a purple one for the output and a green one for ground. Connect yours by following these steps: Turn off the JackBord. Connect a red female jumper to the rightmost pin of the sensor (note: this is with the sensor facing up as in the picture above). Connect a green or black jumper wire to the far left ground pin. Connect a jumper for the output to the center pin. In our case we used a purple jumper. Check your sensor connections with the picture below. Here we have used a red wire for 5V, a purple one for the output and a green one for ground. Connecting the Sensor to the JackBord Now that we have the jumpers connected to the sensor we need to connect the other ends to the JackBord. These connections are listed in the table below. Connection Steps: We are going to connect the sensor to port Pin A1 on port A. We will also use port A's ground and 5V power line to keep things tidy. Follow these steps to connect the sensor to the JackBord: Turn off the JackBord Connect the green ground wire from the sensor to the ground pin on port A. Connect the red power wire from the sensor to the +5V pin on port A. Connect the purple output wire from the sensor to port pin A1 on the JackBord. Once you have made the connections check them against the picture below and make sure they match. Compare your connections with these pictures. Once you are sure they are ok carry on to the usage instructions below. Using the Sensor with the JackBord Turn on the JackBord and go to the dashboard. We can use the button press and release commands, with this sensor so we can get the JackBord to take certain actions in response to the state of the sensor. As stated above, when an object is detected the output will go high (3V) and once the object leaves the sensors view the output will go back to being low (0V). Because this is the opposite of a buttons operation we need to use the button release command btr to deal with the detection event and the button press btp command to deal with the non detection event. Example Commands: The commands below setup the sensor on port A1 so that when an object is detected the USER LED on the front of the JackBord will be turned on, this is accomplished by the btr command. The USER LED will turn off once the object leaves the field and this is because of the btp command. btr a1 l1 1 btp a1 l1 0 Previous Next

LED no USER LED 1 Front (block 2 & 3) 2 Internal USER LED 2 (block 3) 3 Internal USER LED 3 (block 3) R The red value, 0 to 255 G The green value, 0 to 255 B The blue value, 0 to 255 Examples suled 3 255 255 255 Set USER LED 3 to white suled 1 128 0 0 Set the front USER LED to red Notes This command is for the USER LEDs. The USER LEDs can also be controlled on port l. Where l1 is the front USER LED, so l1 1 turns the front USER LED on. l1 15 sets the front USER LED to be purple and so on.

< Back Actuator Commands calstr - Run the steering limit switch calibration routine Purpose This routine is for robots using a linear actuator steering system with left, center and right steering limit switches fitted. The routine establishes the range of the steering actuator and the location of the centre limit switch in terms of pulses applied to the linear actuator. It also determines the travel length of the actuator in terms of the number of pulses required to move it through it’s full range. Syntax calstr Notes This is for robots with a linear actuator steering system. Once the calibration has been successfully completed the steering system will automatically use the new values so that the various built in steering functions will work as expected. mvsa - Move linear steering actuator Purpose Moves the steering actuator into a new position. Syntax mvsa pos Arguments pos The new position measured in pulses required to reach that position. Examples mvsa 0 mvsa 100 Notes The required pulses need to be determined by running the calstr command first. vdl - Drive System Limit Switch Status Purpose Display the current Drive System Limit Switch Status Syntax vdl Example > vdl < LAct Steering: Limits Regs L0C0R0 HW State Cal L 0 C 0 R 0 C 0 R 0 POS 0
