The circuit of the Arduino-based FM receiver, shown in Fig. 2, is built around Arduino UNO board (board1), TEA5767 radio receiver module (FM1), LM386 low-power amplifier (IC1), 16×2 LCD (LCD1) and ...

He further explains that, with the Arduino Uno, you can remove the reference capacitor from the circuit, and simply use the stray capacitance present in the board and microcontroller, which can be ...

The Arduino Uno-compatible board has an MCS-51 (often called 8051 instead) instead of the usual ATmega328P/ATmega168. Specifically, [ElectroBoy] uses the AT89S52 .

A few of resistors and capacitors “condition” the audio signal. The left-hand side of the schematic includes the Arduino Uno’s ATmega328 and the components located on the Extension Shield. At the ...

Arduino Uno R4 WiFi comes with built-in Wi-Fi and Bluetooth capabilities, along with additional pins and a new, ... The GND pin, which you already know, is for grounding your circuit.
