It's built for rapid prototyping, learning, and creating interactive projects without external components. Pre-wired to standard pins, it lets you focus on coding right out of the box.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCompatible Boards\u003c\/td\u003e\n\u003ctd\u003eArduino Uno, Leonardo (5V logic)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDisplay\u003c\/td\u003e\n\u003ctd\u003e4-digit 7-segment (74HC595 shift register)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eUser Input\u003c\/td\u003e\n\u003ctd\u003e3 push-buttons (S1, S2, S3)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSensors\u003c\/td\u003e\n\u003ctd\u003eNTC thermistor (temperature), potentiometer\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutputs\u003c\/td\u003e\n\u003ctd\u003eActive buzzer, 4 indicator LEDs\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCommunication\u003c\/td\u003e\n\u003ctd\u003e38kHz IR receiver for remote control\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/arduino-digital-clock-kit-build-your-own-real-time-clock-with-ds3231-rtc\"\u003eDigital clock that shows time and temperature on the 7-segment LEDs.\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eIR remote-controlled timer or counter with button overrides.\u003c\/li\u003e\n  \u003cli\u003eReaction game with score tracking and buzzer feedback.\u003c\/li\u003e\n  \u003cli\u003eTemperature alarm that triggers the buzzer when a threshold is crossed.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis shield is designed for Arduino Uno and Leonardo boards with standard header spacing. It also works with Mega 2560 (some pin mapping identical, but check shift-register pins) and other 5V Arduinos using a breakout. The 7-segment uses digital pins 8 (data), 9 (clock), and 10 (latch); buttons read on A1–A3; buzzer on D3; thermistor on A0; potentiometer on A4; IR receiver on D11. No soldering required—simply stack it onto your board.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eStack the shield directly onto the Arduino, aligning pin 1. Power is drawn from the 5V rail. The shift-register pins (8,9,10) are dedicated to the display; avoid using them for other output if the display is active. Buttons are normally open and require internal pull-ups enabled in code. The IR receiver outputs digital data on pin 11, and the buzzer is active low on pin 3. Always verify silkscreen labels—slight variants may swap sensor pins.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.\u003c\/p\u003e\n\n\u003cdetails\u003e\u003csummary\u003eIs this compatible with Arduino Mega 2560?\u003c\/summary\u003e\u003cp\u003eYes, it fits and works. The shift-register pins (8,9,10) remain the same on the Mega, and the analog pins for buttons and sensors are available. Just check that your sketch doesn’t conflict with Mega-specific pins used by the shield.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eDo I need to solder headers or components?\u003c\/summary\u003e\u003cp\u003eNo, the shield arrives fully assembled with all components and headers soldered. Plug it directly onto your Arduino.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eCan I use the shield with an Arduino Nano?\u003c\/summary\u003e\u003cp\u003eNot directly, as the Nano’s pin layout differs. You can connect it using a breadboard and jumper wires, mapping the shield’s pins to the corresponding Nano pins, but it won't physically stack.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
