Today just received from Demetrius Dozier 8 Adafruit LoLa Radio Transceivers modules - 4 different pairs - RFM69HCW - 915 MHz, RFM69HCW - 433 MHz, RFM95W - 915 MHz, and RFM95W - 433 MHz.
Thank you Demetrius Dozier your generosity, and support for the Visuino Community!
Already looking into the Visuino support for the modules!
Not only he sent so many modules, but even full set of SMD and Edge-Launch SMA antenna connectors for them:
I will also plan to present 3 other sessions. I already announced my Visuino Sessions and will see to announce my .NET session in the next couple of days. You can see the complete list of sessions here:
If you are in the area, please join the sessions. The Conference is Free! Please also vote for the session, if you plan to attend, so the organizers can assign room with proper size :-)
Last year I attended the conference (You can actually see me on the picture above almost right in the center :-D ), and it was a great event! Even if you are not interested in my sessions, please check out all the great sessions by the rest of the presenters!
Please note that the site seems to be very popular, and sometimes the server is overwhelmed and timesout. If you get timeout error, please try later again!
Few days ago, I received this great Smart Car kit from Elegoo generously donated to support the Visuino development! In the previous blog posts, I showed you the first 4 steps of the assembly process. Now I will show you how to connect all the parts together and complete the robot.
The Smart Car kit comes with 2 sets of Female-Female jumper cables. Short and long. I initially tried to use the short ones for the Ultrasonic Ranger, but they seem too short, so peal 4 wires from the long set of cables (In my case Yellow, Orange Green and Brown):
Connect the wires to the Ultrasonic ranger as shown on the picture - from the back left to right start with the Brown wire:
Connect the other end of the Brown wire (the one connected to the left pin from the back of the Ultrasonic Sensor) to the Ground pin of the A5 sensor connection points of the Sensor Shield:
Connect the Yellow Wire (the one connected to the right pin from the back of the Ultrasonic Sensor) to the Power pin of the A5 sensor connection points of the Sensor Shield:
Connect the Orange Wire (the one connected to the third pin from the left of the Ultrasonic Sensor) to the A5 Signal pin of the sensor connection points of the Sensor Shield:
Connect the last wire - Red Wire to the A4 Signal pin of the sensor connection points of the Sensor Shield:
Take the remaining short connection with white connector on one side, and black on the other, and connect the white connector to the Infrared Remote Sensor:
Connect the black connector of the wire to the connection points for pin 12 on the Sensor Shield, so the black wire is connected to ground, and the white to signal:
Split 6 long Female-Female jumper wires - in my case Green, Blue, Purple, Gray, White and Black:
Connect the wires to the L298N Motor Driver module control connector as shown on the pictures:
Now it is time to connect the 2 layers of the Chassis together. The Spacers and the Screws for them are packaged in 2 clearly labeled bags:
Take them out of the bags,
Flip the bottom layer of the Chassis - the one with the motors upside down and insert one of the screws from the bottom trough one of the corner holes, then screw the spacer on it from the top:
Do the same with the rest of the spacers:
Connect the power connector to the Arduino board:
Connect the Red Power wire from the power connector to the first connection point of the power connector of the L298N Motor Driver module:
Connect the Black Ground wire from the power connector to the second connection point of the power connector of the L298N Motor Driver module:
Grab all the cables that have unconnected ends together:
Push them through the big hole in the top Chassis layer from the bottom, so the unconnected ends appear on the top:
Place the top layer of the Chassis over the spacers, so the corner holes match, and insert and tighten screws through the holes.
I also inserted the power wires for the motor driver through the same big hole, to reduce clutter:
Connect the 6 wires from the motor shield to the signal pins 5 to 10 of the digital sensor pins, connecting the wire from the left pin (Green Wire) of the L298N Motor Driver module to pin 10, and the rest of the wires in order to the following pins until pin 5:
Connect the wire from the Right Line Following Sensor when looking from the back of the cart in normal upside position (The sensor on the opposite side of the power connector for the Arduino), to the points for pin 2 on the Sensor Shield, so the black wire is connected to ground, and the white to signal:
Connect the wire from the Center Line Following Sensor, to the points for pin 4 on the Sensor Shield, so the black wire is connected to ground, and the white to signal:
Connect the wire from the Left Line Following Sensor when looking from the back of the cart in normal upside position (The sensor on the opposite side of the power connector for the Arduino), to the points for pin 11 on the Sensor Shield, so the black wire is connected to ground, and the white to signal:
Optionally we can also install the Bluetooth module. The Sensor Shield has dedicated connector for it:
Be aware that when the Bluetooth module is installed, you will not be able to program the Arduino as it uses the same serial interface. You will need to remove the Bluetooth module every time you program the Arduino.
We can now also charge the rechargeable batteries. The Smart Car robot contains a battery charger. Make sure you use the included charger to charge the batteries, as otherwise you may damage them, or even cause fire!
Unpack the batteries and the charger:
Insert the batteries into the charger making sure you match the + and - as labeled on the charger:
Connect the charger to power. The LEDs will light in red indicating charging the batteries:
Once the batteries are charged, the LEDs will turn greenish:
The Smart Car Robot is complete and ready to program. I will see to make some tutorials on programming it with Visuino in the coming days.
