Automatic Laser Gun

Laser Gun - ESP driver This is the driver of ESP8266 for the Timed Laser Gun project (here the WebInterface), a remix ofRemotely controlled torch robot by JJRobots. Timed Laser Gun project is an automatic toy to let you cat play with laser pointer. I used an ESP to control the servo motors and a RTC to provide a correct timing to schedule the events. Running on ESP NodeMCU To programm the ESP, use the Arduino IDE, then follow this step : Go on File > Preferences, and change the URL of Board Manager with "http://arduino.esp8266.com/package_esp8266com_index.json", then click OK Now go on Tools > Board:Arduino one > Board Managers Search For "esp8266" and Click Install ( it will take a while ) After installation go back on Tools > Board:Arduino one and click on "NodeMCU 0.9 (ESP-12E Module)" Now you can connect it and lunch the Load process Build Hardware The hardware part is made by : x1 ESP8266 NodeMCU x2 Servo motor 9g x1 RTC I used an RTC, to have a real timinig and schedule the event, but you can also use a Virtual RTC to simulate the timer ( obviously it will not be precise like RTC but you can every day sync with a remote server and it will be enough ). Here the class I wrote and here how to use it : void setup(){ //String TimeNow = YourCustomTimeService.getStringTime(); // this in case you have a service that provide this string date format dd/mm/yyyy HH:mm:ss String TimeNow = "dd/mm/yyyy HH:mm:ss"; String d = TimeNow.substring(0,2); String h = TimeNow.substring(3,5); String m = TimeNow.substring(6,8); String s = TimeNow.substring(9,11); rtc_timer = Rtc(); rtc_timer.setup(d.toInt(), h.toInt(),m.toInt(),s.toInt()); } void loop() { rtc_timer.loopTime(); int seconds = rtc_timer.getSeconds(); int minutes = rtc_timer.getMinutes(); int hours = rtc_timer.getHours(); int days = rtc_timer.getDays(); // here you will use it } I removed the soldered pins just to save space, but I think you can do it without desoldering, just force a little bit. Use this ( I not if is ugly I'm not a painter :D ) datasheet to build the hardware, I just make a simple list of connection points: Servo X GND -> GND Vcc -> Vcc ( +5 ) Sign -> D6 Servo Y GND -> GND Vcc -> Vcc ( +5 ) Sign -> D5 RTC GND -> GND Vcc -> Vcc ( +3 ) SDA -> D2 SCL -> D1 Battery (do not plug microUSB and connect battery simultaneously, I didn't try but I suggest to do not try) Positive -> Vcc ( +5 ) Negative -> GND Here the datasheet Here my result Then put all in the base case, use 2/3 mm screws ( I'm not sure ) to fix the ESP to the base, and that's it, program it and enjoy it.
