这不是电动自行车吗？为什么要用电动车的接口？

本帖最后由 serialworld 于 2025-3-22 07:07 编辑上一版的代码存储开关阀门时间的部分有Bug,这一版更新了一下。另外，还加入输入控制参数的正确性检查。目前手动控制还以有个Bug,待后面完善。 /* Automatic Watering System 2025.03.01 */ #include <Ticker.h> #include <RtcDS1302.h> #include <EEPROM.h> #include "TM1637.h" #define VALVE_PIN1 8 #define VALVE_PIN2 9 #define KEY_PIN 2 #define MANUAL_5_min 300000 //5 minutes #define MANUAL_10_min 120000 //2 minutes #define DISPLAY_TIME_INTERVAL 5000 //5 second #define DAYS 8 //0 day is today, 1 day is tomorrow ... #define NUMBEROFTIMES 2 #define CLK 11 //pins definitions for TM1637 and can be changed to other ports #define DIO 10 #define KEY_DELAY 15 TM1637 tm1637(CLK, DIO); ThreeWire myWire(4, 5, 3); // IO, SCLK, CE RtcDS1302<ThreeWire> Rtc(myWire); const int ledPin = LED_BUILTIN; const int valvePin[] = { VALVE_PIN1, VALVE_PIN2 }; const int on_time = 0; const int off_time = 1; const int days_of_plan = DAYS; const int minutes_per_day = 1440; const int minutes_per_hour = 60; int interval_day = 0; int interval_time_per_day = 10; int day_work_complete = 0; int valve_state = 0; //0 open, 1 close volatile int key_state = 0; //the number of minutes since midnight unsigned int onOffTimes[days_of_plan][NUMBEROFTIMES] = { { 600, 604 }, { 600, 604 }, { 600, 604 }, { 600, 604 }, { 600, 604 }, { 600, 604 }, { 600, 604 }, { 600, 604 } }; unsigned int onOffTimes_eeprom[days_of_plan][NUMBEROFTIMES] = {}; int8_t TimeDisp[] = { 0x00, 0x00, 0x00, 0x00 }; RtcDateTime now; RtcDateTime start_time; void close_all_valve(); void display_time(); Ticker timer_manual_10_min(close_all_valve, MANUAL_10_min, 1); // Ticker timer_manual_5_min(close_all_valve, MANUAL_5_min); Ticker timer_display_time(display_time, DISPLAY_TIME_INTERVAL); void close_all_valve() { valve_close(0); valve_close(1); Serial.println("in close all function"); // timer_manual_10_min.stop(); } // valve open void valve_open(int i) { digitalWrite(valvePin[i], LOW); tm1637.displayStr("Open"); valve_state = 1; } // valve close void valve_close(int i) { digitalWrite(valvePin[i], HIGH); tm1637.displayStr("Clos"); valve_state = 0; } void display_time() { now = Rtc.GetDateTime(); // Serial.println(); // Serial.println(); // printDateTime(now); // Serial.println(); // printDateTime(start_time); // Serial.println(); // Serial.print("Days from start:"); // Serial.print(now.TotalDays() - start_time.TotalDays()); // Serial.println(); Serial.print("Days of week is "); Serial.println(now.DayOfWeek()); Serial.println(); if (!now.IsValid()) { // Common Causes: // 1) the battery on the device is low or even missing and the power line was disconnected Serial.println("RTC lost confidence in the DateTime!"); return; } TimeDisp[0] = now.Hour() / 10; TimeDisp[1] = now.Hour() % 10; TimeDisp[2] = now.Minute() / 10; TimeDisp[3] = now.Minute() % 10; tm1637.display(TimeDisp); tm1637.point(now.Second() % 2); // Serial.println(); // Serial.println(); // Serial.print("Type 'P' to print settings or "); // Serial.println("'S2N13:45' to set valve 2 ON time to 13:34"); // Serial.println("Please enter O to open valves"); // Serial.println("Please enter C to close valves"); } void setup() { //start serial connection Serial.begin(9600); //configure pin 2 as an input and enable the internal pull-up resistor pinMode(ledPin, OUTPUT); pinMode(valvePin[0], OUTPUT); pinMode(valvePin[1], OUTPUT); pinMode(KEY_PIN, INPUT_PULLUP); digitalWrite(valvePin[0], HIGH); // close valve at begin digitalWrite(ledPin, LOW); // LED off //RTC information display Serial.print("compiled: "); Serial.print(__DATE__); Serial.println(__TIME__); Rtc.Begin(); RtcDateTime compiled = RtcDateTime(__DATE__, __TIME__); printDateTime(compiled); Serial.println(); if (!Rtc.IsDateTimeValid()) { // Common Causes: // 1) first time you ran and the device wasn't running yet // 2) the battery on the device is low or even missing Serial.println("RTC lost confidence in the DateTime!"); Rtc.SetDateTime(compiled); } if (Rtc.GetIsWriteProtected()) { Serial.println("RTC was write protected, enabling writing now"); Rtc.SetIsWriteProtected(false); } if (!Rtc.GetIsRunning()) { Serial.println("RTC was not actively running, starting now"); Rtc.SetIsRunning(true); } now = Rtc.GetDateTime(); if (now < compiled) { Serial.println("RTC is older than compile time!

回复了主题帖：【新年花灯】STM32 F030 点亮WS2812流水灯

本帖最后由 serialworld 于 2025-3-22 06:53 编辑具体实现的原理是借鉴了帖子WS2812灯珠的STM32驱动是用DMA+PWM相结合实现的。具体代码如下，供大家参考。硬件使用的是STM32F0开发板，外壳使用的是一个开关面板的暗盒。 /* USER CODE BEGIN Header */ /** ****************************************************************************** * @File : main.c * @brief : Main program body ****************************************************************************** ** This notice applies to any and all portions of this file * that are not between comment pairs USER CODE BEGIN and * USER CODE END.

本帖最后由 serialworld 于 2025-3-8 17:25 编辑秦天qintian0303 发表于 2025-3-7 07:12 总感觉这种自动浇水系统如果不应用在大规模上就有点浪费了我看了一下网上卖的自动浇花的基本都是家用的，当然体积都比我这个DIY小不少。一般也不用电磁阀，用小水泵供水。这个体积大，主要是使用了现成的模块。尤其是用了arduino uno开发板，要是换成其他开发板体积会小一些。

本帖最后由 serialworld 于 2025-3-8 17:16 编辑 kit7828 发表于 2025-3-8 14:55 潜水泵寿命不长吗？有具体的测试数据吗？这确实没有测试，只是一般的小水泵都是有刷电机。电机寿命受电刷寿命的影响。不过如果只是浇花的，不会长时间运行，寿命也不是太大的问题。鱼缸用的潜水泵，寿命应该是很长的，用的应该是无刷电机。

本帖最后由 serialworld 于 2025-3-5 21:13 编辑在之前的基础上增加了物理按键，LED数码管。按键用于手动控制，而LED数码管用来显示电磁阀的状态和时间。完善后的硬件照片如下。软件方面也正在完善，目前已经可以显示时间了。硬件方面，考虑到电磁阀发热较大，担心因为单片机死机或继电器故障而导致电磁阀长时间通电，使得电磁阀温度温度过高，导致损坏，可以增加温度保护功能。目前，考虑使用温度开关进行保护。目前制作的优点和不足：优点： 1..基本使用可以直接外购的模块，制作比较方便； 2..使用Arduino uno开发板开发速度快； 3.交流供电不用考虑电池更换问题.； 4.不使用电动水泵，寿命长。缺点： 1.体积大，使用模块和电磁阀，体积比较大； 2.不使用电动水泵，浇花的水流量小； 3.使用交流供电，需要附近有电源； 4.模块之间使用杜邦线连接可靠性差； 5.制作成本高,主要是arduino开发板比较贵。软件方面的计划实现如下功能：一周七天可以设置开启时间和关闭时间；手动开启和关闭，手动开始2分钟后自动关闭；时间显示功能；第二帖第一帖

walker2048 发表于 2025-2-24 01:19 如果你需要管理的植物用的水不多，直接买二手茶吧机水泵就行了，还能通过计算通电时间来算出水量。我小鱼缸 ... 茶吧水泵价格不高，直接用水泵也是不错的一个方案。

本帖最后由 serialworld 于 2025-2-23 19:24 编辑经过物料采购后终于凑齐了所有物料，可以开始搭建硬件了。主要工作是如何布局相应的模块，好在选的盒子足够大，布局也没有费太多的时间。比较费事的是给安装底板打孔，孔的位置一定要准确。不过手工操作，加上动手能力有限，还是有几个孔打的有些歪。DIY吗，将就一下了。组装后的结果见下图。之后烧录了一个简单的程序，测试了一下功能，没有什么问题。只是发现一个现象，电磁阀打开时，开一会儿就烫手，大概计算了一下功率大概4W，还是挺大了。这个倒是有点出乎我的意料。之前也没有接触过电磁阀的应用，烫手也应该没有问题吧。另外测试了一下水流情况，当高度差大于50CM的时候，水流还是可以的，毕竟只是浇花，可以通过延长电磁阀打开时间来增加总的水量。下一步是软件方面的工作，需要花一些时间了。对了，硬件方面的工作也没有完全结束。后续应该会增加一个手动控制的按键及一个温度传感器。

Jacktang 发表于 2025-2-15 10:09 执行部分建议使用常闭型电磁阀。如12V/24V，响应时间≤0.5秒，可减少开关延迟对虹吸水流量的影响目前选用的的确是12V的电磁阀，使用的是净水器2分的电磁阀。不知道是否选用的管子太细。另外开关延迟如何对虹吸水流产生影响，不明白。

本帖最后由 serialworld 于 2025-2-15 22:07 编辑一直想做一个自动浇花的系统，但是迟迟没有开始。最近准备开始制作。目标：仿照图书《爱上Arduino》的自动灌溉系统的使用国内可以购买的物料进行制作，完成度在80%左右，也会改动原有的系统。初步的构想的功能目标： 1.室内使用，自动定时浇花，支持最大5盆花，不使用水泵，使用虹吸方式供水，交流供电 2.尽量成为有点实用的东西，不能成为又增加的没有的东西初步计划使用的物料可能包括： 1.时钟模块 2.Arduino UN开发板或其他单片机开发板 3.继电器模块 4.电磁阀 12V 2分 5.水管 2分外径约6.5mm，内径4.1mm，水桶等 6.电源 12V 1.5A 7.外盒 160X160X90 8.固定模块用底板150x150x2 9.M2,M3 等螺丝 10.开关按键 11.Arduino原型开发板 12.导线排针计划时间：1个月目前已经准备的物料如下图，目前还缺少时钟模块和模块固定底板。陆续采购中... 目前制作还未开始，还请大家多提意见！！！
