Dual Channel Bluetooth Controller | How to Make a Bluetooth Controller

📌JLCPCB Prototype for $2(Any Color): https://jlcpcb.com

Hello Dear, Welcome to the new blog. In this video tutorial, I will show you How to make a dual channel Bluetooth controller module. This really simple project. I am using dual-channel relay but you can use quad-channel or octal channel relay. I am a simulation circuit diagram from easyeda.com for simulate circuit & design PCB file. for the programming section, I am using the remotexy.com website which is a cool website for automatically generate code. Parts list below. The Parts required for this Project 1. Atmega 328p IC

2. Relay 05Vx2

3. Transistor BC547

4. Resistor 1K x5

5. Resistor 10K x1

6. LED

7. HC05 Bluetooth Sensor

8. IC Base 28 Pin

9. AC Terminal Block 2pin x2

10. AC Terminal Block 3Pin

11. 22pf Capacitor

12. 10uf, 50V Capacitor

13. Female to Male IC Rail

14. 1N4007 Diode

15. 16Mhz Crystal

16. AC Lamp x2
