Create a beginner-friendly Arduino Uno slot machine (casino-style number game) using three separate single-digit 7-segment LED displays. Components and features: - Arduino Uno - Three separate single-digit 7-segment LED displays - Current-limiting resistors for all LED segments - One START button to spin the numbers - One RESET button to reset the game and return to the initial state - One separate indicator LED that flashes when all three digits are identical (for example, 777, 333, or 999) - The three digits spin and then stop on random numbers from 0 to 9 - If all three digits match, flash the indicator LED several times and then stop - If the digits do not match, the indicator LED stays off - The RESET button must immediately stop the current game, turn off the indicator LED, clear the displayed result if possible, and return the game to its initial state Please provide: 1. A complete, readable circuit schematic. 2. Exact Arduino pin assignments for every display segment, both buttons, and the indicator LED. 3. A complete component list with quantities and values. 4. Correct wiring instructions, including pull-up or pull-down resistors for the buttons. 5. Arduino Uno code implementing all features, with comments. 6. Check the circuit for wiring errors and simulate it if possible. 7. Specify whether the 7-segment displays use a common cathode or common anode. 8. Keep the design low-cost and suitable for a beginner. Important: Do not connect LED segments directly to Arduino pins without current-limiting resistors. Check the current limits of the Arduino pins and recommend driver transistors or a display driver IC if needed.

Create a complete hardwired electrical relay ladder diagram for a six-player game-show buzzer system. Do not use a PLC, microcontroller, Arduino, or software control. **Control power:** 24 VDC. **Components:** - One 24 VDC power supply with appropriately rated circuit protection. - Six momentary normally open player pushbuttons, PB1–PB6. - Six 24 VDC plug-in relay coils, K1–K6, one per player. - Six 24 VDC indicator lamps, H1–H6. - One master-ready relay K0. - One host RESET pushbutton with a normally closed contact. **Required operation:** 1. When ready, all six indicator lamps are off. 2. The first player to press their button energizes and latches their corresponding relay. 3. That player's indicator lamp turns on and remains on after the button is released. 4. All other player relays are electrically interlocked and prevented from latching. 5. The host presses RESET to de-energize the selected player relay, turn off the lamp, and restore the ready state. 6. Use hardwired auxiliary contacts, seal-in circuits, and electrical interlocking. 7. Draw conventional ladder-style rungs with +24 VDC and 0 V rails. 8. Label all pushbuttons, relay coils, NO/NC contacts, indicator lamps, fuses, and terminal blocks. 9. Include a separate physical wiring schematic showing the relay sockets and terminal connections. 10. Flag the limitation that ordinary electromechanical relays may not guarantee priority if multiple players press simultaneously. Generate an editable diagram if supported. Clearly distinguish the functional ladder diagram from the physical wiring schematic.

**PROGETTO: SCHEMA ELETTRICO DI ACCENSIONE DI DUE LAMPADE DA DUE PUNTI CON DUE PULSANTI E MODULO SHELLY** Realizzare uno schema elettrico dettagliato, chiaro e leggibile, con collegamenti reali tra i morsetti dei componenti. Non realizzare una semplice piantina e non usare collegamenti indicativi. **Componenti** * Due lampade: L1 e L2. * Due pulsanti momentanei normalmente aperti: P1 e P2. * Un modulo Shelly, con morsetti identificati esattamente secondo il modello utilizzato. * Alimentazione di rete 230 V AC: fase L, neutro N e conduttore di protezione PE. * Scatole da incasso 503 per i componenti previsti. **Funzionamento richiesto** Entrambi i pulsanti devono comandare l'accensione e lo spegnimento delle due lampade da entrambi i punti di comando, secondo la logica prevista dal modulo Shelly. Le due lampade devono accendersi e spegnersi insieme. **Come deve essere disegnato lo schema** 1. Disegnare ogni componente separatamente e assegnargli un'etichetta univoca. 2. Mostrare i morsetti reali del modulo Shelly e i contatti dei due pulsanti. 3. Tracciare ogni singolo filo dal morsetto di partenza a quello di arrivo. 4. Indicare vicino a ogni filo il nome del conduttore e la sua destinazione. 5. Mostrare chiaramente le giunzioni elettriche con punti di connessione; nessun incrocio deve essere interpretato come una giunzione se non è indicato. 6. Separare graficamente i collegamenti di alimentazione, comando e uscita verso le lampade. 7. Inserire una legenda dei conduttori e una tabella con origine e destinazione di ogni filo. 8.
