It reads analogs for 19// 20 the blood sugar number & joystick, turns lights off at dark, knows what time it 21 is, 22// can communicate remotely, switch meter feeds, control blinkey lights, 23 measure 24// distance, and move steppers and servos - all at once! 25// 26// 27 We're down to the last 5 D's, but we still have 8 AI's 28// 29const float Version 30 = 5.09; 31// 32// V5.09 - 11Feb22 - MML - Add insulin estimator & PO Box sim using 33 pot as input device 34// V5.08 - 08Feb22 - MML - Clean up LCD layout 35// V5.07 36 - 07Feb22 - MML - Make 9-ball biker & get VU meter wired 37// V5.06 - 06Feb22 - 38 MML - Add Magic 8-ball 39// V5.05 - 05Feb22 - MML - Get 2nd servo running - All 40 remote buttons working, codes verified 41// V5.04 - 31Jan22 - MML - Stepper fixed 42 - odd phase ordering and setting RPM fixed it 43// V5.03 - 30Jan22 - MML - Servo 44 working, still wirinjg, diddle with stepper 45// V5.02 - 27Jan22 - MML - (Cont.) 46 - Lots working - Echo & clock up, 47// V5.01 - 26Jan22 - MML - (Cont.) 48// V5.00 49 - 24Jan22 - MML - Upgrade IO's (again) 50// V4.03 - 12Jan22 - MML - Test IR remote 51// 52 V4.02 - 11Jan22 - MML - Work on Touch sw & knock 53// V4.01 - 10Jan22 - MML - Try 54 to get hardware to run - everything lights up 55// V4.00 - 08Jan22 - MML - Align 56 I/O's with "as built" hardware 57// V3.01 - 16Dec21 - MML - Get RTC and rangerfinder 58 working 59// V3.00 - 14Dec21 - MML - Get 2nd lcd working 60// V2.00 - 13Dec21 61 - MML - Strip down to get clean compile 62// V1.01 - 10Dec21 - MML - Continue baseline 63// 64 V1.00 - 06Dec21 - MML - Baseline with LCD - Mega 2650 has built in pullups 65// 66// 67 ---------------------------------------------------------------------------- 68// 69 ---------------------------------------------------------------------------- 70// 71// 72 Device Master List 73// 74// Mega 2560 Processor 75// +12 to +5 Vreg 76 & Buss Bars 77// I2C devices 78// 1602 LCD Command display 79// 2004 80 LCD #1 Indoor Display 81// 2004 LCD #2 Outdoor Display 82// BHT280 83 Baro Barometric sensor 84// 85// Echo Rangefinder 86// Traffic Light 87// 88 FM Radio (Button) <<====== OUT - Real Radio in 89// Analog VU meter Subsystem 90// 91 IR remote command in 92// LDR light sensor 93// Analog Joystick with push sw 94// 95// 96 K1-4, 5, & 6 relays 97// RTC 98// DHT11 Temp/Humidity (Indoor) 99// ESP-01 WiFi 100 - From Outdoor DHT-11 101// Touch Sensor 102// Servo output - Haven't added IO's 103 yet or quite figured out what this will do. 104// I'm leaning to a secret compartment 105 with a hidden release and maybe the knock sensor 106// Knock sensor 107// 108// 109 ================================== 110// Start of Pin Constants 111// ================================== 112// 113// 114 Analogs first 115// 116int xx = 0; //Placeholder value 117// 118const 119 int Vnoise = A2; // Random number seed is open AI 120const int Vin = A3; 121 //Power supply direct output monitor - NOT USED 122// 123const int I2C_A4 = 124 A4; // RESERVED 125const int I2C_A5 = A5; // RESERVED 126// 127// Float constant 128// 129const 130 float VoltsPerBit = (5.0 / 1024.0); //Compute bit weight based on +5 Vin max 131// 132// 133 Int constant implied 134// 135const int VinAux5 = A12; //+5v input monitor via 136 card 137// 138// Joystick - A13 & 14 not on Uno 139// See Also Zaxis DI 140// 141const 142 int Yaxis = A13; //Joystick y 143const int Xaxis = A14; //Joystick X 144// 145const 146 int Wiper = A15; //Wiper from 5k pot 147// 148// Analogs end 149// ----------- 150// 151 Now digitals 152// 153// D0 and D1 are rx/tx for serial programming 154// 155const 156 int RPM = 15; // Top end is ~15 from what I've read, works at 157 15 158const int StepsPerRevolution = 2048; // 28BYJ-48 Stepper - this # may not 159 be exact, docs differ 160// 161// Stepper motor pins - Powered by Aux +5 - Works! 162// 163const 164 int StepA = 2; //Stepper Motor Phase A 165const int StepB = 3; //Stepper 166 Motor Phase B 167const int StepC = 4; //Stepper Motor Phase C 168const int 169 StepD = 5; //Stepper Motor Phase D 170// 171// 6/7 L & R PWM 172// 173const 174 int VULeft = 6; // Signal to VU meter Left 175const int VURight = 7; // 176 Ditto right 177// 178const int MotorSpeed = 8; // PWM for motor speed control 179 180// 181// Servo needs a PWM output.

3D .STL Print File - Joystick Box for Arduino Analog Joystick w/pushbutton action
The X-Y analog joystick has a push button for Z. The Arduino module has four #4 thru holes on a .80" x 1.05" grid. This box has a spherical opening that exactly fits the joystick. A cutout is provided in the side for cable egress. The four joystick mounting holes need to be tapped 4-40 prior to use. The four cover screw holes will accept a 6-32 x 1/2" screw without threading - do not over torque. The corners are rounded for comfort. For correct X-Y orientation the cable exits left.

3D .STL print file - HC-SR04 Sonar Rangefinder Rear Panel Mount
This is a panel mount for the HC-SR04 ultrasonic rangefinder module commonly found in Arduino kits. The mount has two #4 thru holes for attachment to the panel. The HC-SR04 module firmly slips into place and a drop of superglue can be used for a permanent grip if so desired. Use 90% infill for strength when printing.

3D .STL print file - SDA/SCL Buss bars for 12 ga wire.
Want multiple I2C devices but don't have connections? Add a 12 ga buss bar for each signal SDA and SCL. Signal name embossed in base. Support towers are filleted for strength. Use 12 ga solid copper wire as buss bars. Strip a short length of 12-2 house wire and used bare ground as buss. Print at 90% infill for strength.

3D .STL print file - Box with 1/4" hole for toggle switch, screw lid
Need to mount a switch to control power to your project. Add any 1/4" dia switch in the built in hole. Use a soldering iron to melt cable entry notch to match your specific needs. Four corner posts designed to be threaded 6-32 x 1/2". Corners internally filleted for strength. Print at 90% infill for strength.

3D .STL print file - Connector Holder for Dupont connections
Arduino comes with lots of Dupont wires. After use, the connector retention may leave a bit to be desired, especially for long term connection reliability. To solve this problem, here is a little piece that engages the wires on either side of the connection, taking all of the strain off the connection to prevent pull-apart. Print at 90% infill for strength.

3D .STL print file - Vcc & Gnd buss bars for 12 ga wire.
Wiring lots of devices to Arduino is often difficult because there never seem to be enough power and ground connections. The pin boards just don't hold well enough for reliable module powering. Solve the lack of power and ground pins by adding 12 ga solid copper wire buss bars. Strip a few inches of 12-2 wire and use the ground wire for the busses. Solder your individual sensor wires to the busses for reliable power connections. Power with any +5V or +3.3V power source. Two #6 mounting holes provided. Buss voltage (Vcc/Gnd) is integral to the design. Support posts are filleted for strength. Print at 90% infill for strength.

ZIP with Multiple 3D .STL print files - Connector Shrouds for Dupont connections
Single Dupont connectors are difficult to install onto multi-pin connectors. Additionally, single pins don't grip well. Groups of pins, however, are easier to insert and harder to mix up as a unit. These shrouds group sets of 2, 3, 4, 5, 6, & 8 stations into one connector body. Print at 90% infill for strength. Print times 3-15 min.
