This video describes the monitoring of sensor values/ random values using blynk app and FRED IoT Steps to be done in Blynk App & Steps to be done in FRED IoT

1. LECTURE 2
STEPS TO BE DONE IN BLYNK MOBILE APP
+FRED FOR MONITORING RANDOM VALUES

2. BLYNK APP
• BLYNK is a hardware agnostic IoT platform with white label mobile apps,
private clouds, device management, data analytics, and machine
learning.
• Drag and drop IoT apps in minutes

3. STEP 1
Install the Blynk-IoT Mobile App from the Google play store.

4. STEP 2
Registration is required to use it. So, create an account.
(or)
If you have Facebook account you can directly log in with that account.

5. STEP 3
After registration, click on New Project

6. STEP 4
Enter the project name as you wish (example: project 1) Under CHOOSE DEVICE,
select Node-MCU. Under CONNECTION TYPE, select Wi-Fi and click Create.
Authorized token will be sent to your registered mail id. Click Ok.

7. STEP 5
In the project space, select widget box. Its shown as plus symbol

8. STEP 6
Select Gauge under DISPLAYS. Gauge will be display in your project space

GAUGE

9. STEP 7
By just clicking gauge in the project space you will be diverted to Gauge
Settings screen as shown. Under INPUT, select virtual pin V5 (if you are
selecting different virtual pin, you need to change it in the program as well)
and change the variation from 1023 to 200 (it will set the gauge level from 0
to 200).
“Clicking
Back
button
You can
see the
gauge
that
ranges
from
0 to 200
as
Shown”

10. CONGRATULATIONS!
YOU HAVE DONE
THE STEPS TO BE DONE IN BLYNK APP

11. Now Lets see how to send some random values over the
internet using FRED IoT platform without using any hardware
