Intro: Arduino Dynamic Sign
This project was developed with an Arduino nano & a 5x7 segment display without using resistors, but a heat shink was placed on the microcontroller.for dissipating its heat.
Step 1: List of Materials
1 Arduino Nano
1 Common anode, 5X7 Segment Display
1 8.8x8.8x5mm Adhesive Aluminum Heatsink
1 USB-A to USB-mini cable
Step 2: Installing the Arduino Nano
Insert the 5x7 segment display on the Arduino nano without pins by matching display pin1& pin8 with Arduino A5 & D10 respectively.
Step 3: Installing the 8.8x8.8x5mm Adhesive Aluminum Heatsink
Once 5X7 segment display and Arduino nano both soldered together, install the 8.8x8.8x5mm Adhesive Aluminum Heatsink on the microcontroller of your Arduino.
