   * pedestrian traffic light, already hacked to run on regular AC power socket
   * 1 [[webduino]]
-  * cables
+  * 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…)
