So I have an ESP12 board with 16 pins and it would appear the following pins are useable for my sensor input and output.GPIO 2GPIO 5GPIO 4GPIO 13GPIO 12GPIO 14GPIO 16ADCI want to connect firstly a DHT22 sensor which has GND/VCC/DATA wiresWhich pin should I choose for DATA wire and why ? It was connected to pin D2 on an arduino.I want also to connect a BMP180 sensor and its 2 data lines were connected to pins A4 and A5 of the Arduino . Which should I choose and why?I assume the other needed wires for SPI have to be connected somehow too . This would have been done on the Arduino boards through the Ethernet shield .The idea here is to get rid of the Ethernet board.So are the GPIO pins analog or digital ? Perhaps I have to set them upIs there a diagram of these ?All help appreciated.
Neither of those devices will work without pullups unless you've got a breakout module with them built in.
can anyone help me !!!!!!!!i have purchased Esp 8266 12E chip which has specification described in below link ....http://www.amazon.in/Transceiver-ESP8266-ESP-12E-Serial-Wireless/dp/B00RJJHWLA?ie=UTF8&psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00#detail_bullets_idi do not know how to wire it up with arduino uno board to use this chip as web server & receive data from web server to arduino uno board ...... also give me the guidance about pins of chip how & when should use that pins i know basic circuit of esp8266 as mention in below linkhttp://www.amazon.in/ESP8266-Serial-Wireless-Transceiver-Receive/dp/B00YUOAUPC?tag=googinhydr18418-21&tag=googinkenshoo-21&ascsubtag=12be54d8-28d4-42af-85bc-1a325b801ad5so will my new chip esp8266 12E work different form this
