Control LED on EDU:BIT Using IoT Blynk App and Raspberry Pi

Control LED on EDU:BIT Using IoT Blynk App and Raspberry Pi

Introduction

Continue from previous tutorial, since the Raspberry Pi has WiFi, I will try to control the LEDs in EDU:BIT using the Blynk app. The idea is, I will program the Raspberry Pi to read data on the Blynk server, and then send the data to EDU:BIT via serial USB communication. Then the EDU:BIT will control the LED based on the data received.
