This unit will detect the presence of objects at distances of between about 2cm to 30cm. < Back Infrared Obstacle Avoidance This unit will detect the presence of objects at distances of between about 2cm to 30cm. The Infrared Obstacle Avoidance Sensor will detect the presence of objects at distances of between about 2cm to 30cm. It uses an infrared emitting diode to send out an IR signal. Should the signal hit a nearby surface, it will be reflected back to the sensor and the output will go low or to 0V. The potentiometer is used to adjust the sensitivity of the sensor. Turning it anticlockwise will reduce the detection range so it detects closer objects, turning it clockwise increases the sensitivity and it will detect objects farther away. 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 100-degree-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. Sensor Pins The table below lists the pins of the sensor. 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 a 5V supply to work. It needs 3 female to female jumper wires to connect to the JackBord. The output of the sensor can be connected to any of the pins on ports A, B or C. You need the following items: The sensor 3 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 below. 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 to jumper to the rightmost pin of the sensor, note this is with the sensor facing up as in the picture on the left. Connect a green or black jumper wire to the center ground pin. Connect a jumper for the output to the left 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. 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 pictures below and make sure they match. 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. 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). 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 bts command. The USER LED will turn off once the object leaves the field and this is because of the btr command. If needed clear any current button setup using the rstb command. btp a1 l1 1 btr a1 l1 0 Previous Next

This sensor uses an infrared transmitter and receiver to gauge the distance between the sensor and an object near it. It has a digital and an analog output which can be used to control things in response to the presence or absence of an object. < Back Short Range Proximity This sensor uses an infrared transmitter and receiver to gauge the distance between the sensor and an object near it. It has a digital and an analog output which can be used to control things in response to the presence or absence of an object. This sensor uses an infrared transmitter and receiver to gauge the distance between the sensor and an object near it. It has a digital and an analog output which can be used to control things in response to the presence or absence of an object. Quick Commands To get the sensor working, assuming the analog pout is connected to port A a1 and the digital output is connected to a2, enter the commands below at the command prompt. gvr a1 0 100 get a2 The gvr a1 0 100 will result in the value of a1 increasing as an object moves away from the sensor. You can see this change on the LIVE page. Buttons The button press btp and button release btr commands can be used with this sensor. This example uses a button on port a pin a2 and turns the USER LED (l1) on when the sensor detects an object. Removing the object turns it off. btp a2 l1 1 btr a2 l1 0 Videos Getting Started Using the Sensor NOTES AND CAUTIONS: This sensor needs to be adjusted if you want to use the digital output It's maximum range is about 5cm Ambient lighting can affect the performance of the sensor Parts of the Sensor Power LED - Turns on when the power is applied. Detection LED - Turns on when an object is detected. Variable Resistor - Used to adjust the sensitivity of the digital output. Transmitter - The infrared transmitter. Receiver - The infrared receiver. How it Works The transmitter sends an infrared signal and the receiver receives any signal reflected by an object nearby. The closer the objects the stronger the infrared signal that's returned and the lower the output voltage on the analog output. The digital output will go high (3V) when an object is detected and the blue variable resistor sets the trigger threshold for the digital output. Input and Output Pins The sensor has two output pins described below: Connecting the Sensor to the JackBord First bolt the sensor onto port A using an M4 nut and bolt. This is because we're going to use the pins from port A to control the sensor and specifically we need the analog inputs on port A. Take a green jumper wire and connect it to the ground pin on the JackBord and take the other end and connect it to the green ground pin on the sensor. Connect a yellow jumper wire to the 3V pin on the JackBord on port A and then connect the other end to the 3V power input on the sensor. Connect a black jumper wire to the digital output of the sensor and the other end goes to port A pin a2. Connect the analog output of the sensor which is the white pin onto port pin a1 of the JackBord. When you are done it should look like the picture below: Previous Next

We will use an RC servo, which will move its arm in response to the WiFi strength. First, we learn how the JackBord measures WiFi strength, and then we learn how to attach a RC servo to the JackBord. We then create our own dial and attach it to the JackBord and the RC servo. Finally, we put it all together by running a program that controls the servo’s arm based on the strength of the WiFi.
