= Internet/WiFi connected button for ESP-01 (ESP8266) =
Use this circuit to build a button that:
* Wakes up on button press (=RESET)
* Connect to pre-configured WIFI
* Does something in network/internet
* Go to deep sleep afterwards
All programmed in Arduino.
== Electrical connections for Dash-Button with ESP-01 ==
<pre>
+----------------------------+
| ESP8266 ESP-01 |
| RXD VCC |
| GPIO0 RST |
| component GPIO2 CH_PD|
| side GND TXD |
| |
+----------------------------+
GND <-> Minus - from CR123 battery
VCC <-> Plus + from CR123 battery
CH_PD <-> Connect to VCC
RST <-> Connect via 10k to VCC and via button to GND
GPIO0 <-> Connect via 10k to VCC
GPIO2 <-> --[10k]--|<|--VCC (connect via 10k and bright LED to VCC)
TXD <-> not connect
RXD <-> not connect
Optional: Add big capacitor (>100uF, electrolytic) between VCC and GND
</pre>
