Budget:30$
You have to have atleast 5 years of experience in Arduino development using wifi modules.
Please apply only if you have modules ready to start n handy to start now.
Need to connect to android wifi hotspot n arduino ESP8266.
Modules needed:
a)ESP8266,wifi module
b)Arduino UNO
c)4-Relays
d)Android phone with 4G/wifi hot spot
Hi,
1)Need to send schematic diagram,currently have schematic with Arduino,relays(2,3,4,5 uno pins)
2)Need to send Arduino code.
3)Need to demo ,calling webservice and process with conditions,like once u receive 1001 as response then,
relay 1 is on ,
relay 2 is off.
relay 3 is off,
relay 4 is on.
After its processed then need to send confirmation to server back by passing parameter to REST API(will provide)
4)You have to help during installing of hardware n software ,possibly by teamviewer,anydesk if at all any problems,2 webservices should be integrated.
5)This webservice should be called for every 5 seconds continuously 24X7.
HAve more tasks after this is completed.
Will provide API's ,this is few hrs job,need to complete today.
Experience working with Arduinos, ESP8266s, relays, HTTP APIs.
Plan of "Attack":
1.
Poll the API, and check if it needs to change the state. If it does then continue, if not repeat.
2.
Transcoding code into relay states -> Mapping the didgets to states.
3.
Writing the states to the arduino + send ACK message back to REST API.
If desired I can produce code that runs on a NodeMCU too. This way you'll only need your ESP(-like) module without an arduino. You'll need to have at least 4 pins that can be written to.
hii there i am intrested in your job i can give you this all things in 1 day. i have good knowledge in this field from last 5 years and have knowledge of iot better with ESP8266
I have already developed and worked on such project along with android app and web based api services that helps you to control relays and other devices. please check our portfolio for more details about PCB ,IoT development and other.
