This traffic light has been lost somehow around october 2023…

<WRAP round box 60%>
===== Goals =====
  * make use of the pedestrian traffic light: make it controllable via WiFi via MQTT
</WRAP>

===== Resources =====
  * pedestrian traffic light, already hacked to run on regular AC power socket
  * 1 [[webduino]]
  * 2 relay module 3V
  * wires (Dupont and electric cables for 220V AC)
  * USB 5V charger

===== Roadmap =====
  - install esp and relays to control each light individually
  - secure connections using [[wp>veroboard]] or custom-made PCB
  - flash [[webduino]] using Arduino IDE
  - make it blink
  - make it blink according to received MQTT messages
  - enable wifi OTA upgrades
  - add wifimanager
  - make MQTT parameters configurable at runtime ([[https://github.com/prampec/IotWebConf|prampec/IotWebConf]]? see [[https://reddit.com/comments/e4pj1u|this reddit thread]] also)


===== Software =====
Code: https://git.interhacker.space/jeanjack/piedthon

The ESP listens to an MQTT channel at ''sonic.fuz.re'', described in [[:infra:mqtt]].

For testing, using [[https://github.com/shirou/mqttcli|mqttcli]]: ''%%while :; do for I in {0..3}; do mqttcli pub --host sonic.fuz.re -m "$I" -t piedthon/input; sleep 0.5; done; done%%''

or mosquitto ( package mosquitto-clients sur ubuntu ) : ''%%while :; do for I in {0..3}; do mosquitto_pub -h sonic.fuz.re -m "$I" -t piedthon/input; sleep "$J.5"; J="$I";done; done%%''

===== Hardware =====

:!: **RISK OF DEATH OR INJURY: always unplug the traffic light from mains when it is opened as the inside is not insulated at all** :!:

(Describe pinout here, components…)
