Low-Cost Wireless Audio Receiver Prototype

Namaste, mujhe ek Low-Cost Wireless Audio Receiver/Box Prototype banwana hai. Main pehle ek chhota working prototype banwakar uski testing karna chahta hoon. Agar prototype sahi tarike se kaam karta hai, to aage isi design ke bahut saare units banwane hain...
