| # Binary LED | |
| ## Project Description | |
| This is an ESP32 project that uses 5 LEDs to display the binary form of a number received over serial. | |
| ## Hardware Components | |
| - ESP32 DevKit v1 | |
| - 220Ω resistor * 5 | |
| - LED * 5 | |
| ## Circuit Description | |
| Five LEDs are connected to ESP32. LED 1 to 5 are connected to ESP32 pin2, pin4, pin5, pin12, pin13 through 220Ω resistor, respectively. Cathode pin of each LEDs are connected to gnd2. | |
| ## Expected Behavior | |
| When the ESP32 powers up, it should: | |
| 1. Set pin2, pin4, pin5, pin12, pin13 pin mode as OUTPUT | |
| 3. Continuously read the serial monitor, which ranges from 0 to 31 | |
| 4. With LED1 as the LSB and LED5 as the MSB, light up the LEDs that represent 1s in the binary form of the input number | |
| ## Success Criteria | |
| The test is successful when: | |
| 1. When a number is entered via serial input, LEDs corresponding to the bits set to 1 in its binary representation are turned on. | |
| ## Notes for Implementation | |
| - Use Arduino.h library for arduino core. | |
| - Serial input ranges from 0 to 31. | |
| ## Attributes | |
| - To use 220Ω resistor, set the property name "value" to "220 ohm". |
