The internal circuit diagram of the joystick module is shown below: Joystick Module Working The Joystick Module works on the basic principle of two potentiometers and a Gimbal Mechanism. These two mechanisms make it easier to determine the position of the Joystick (right, left, up, and down) ...
To avoid this situation for a "digital only" input you tie the input to the high voltage using a pull-up, and of course the Arduino has internal pull-ups provided for just this operation. The reason for the pull-up is that bias voltages in the CMOS circuit (FET circuit) will set the...
The internal SI473X mute or volume commands will not stop the clicking sound. However, it is possible to solve this problem by adding an extra mute circuit and control it by the MCU (Atmega, ESP32, STM32, ATtiny85 etc).The schematic below shows this approach....
Thus, I decided to use a better RTC module that has an internal clock oscillator and I found the DS3132 Module. Table 1: Major Difference Between DS1307 and DS3231 S.N. DS1307 S.N. DS3231 External Oscillator Clock Circuit 1. External Oscillator Clock Circuit More prone to external ...
1 MHzInternal oscillator9600Derived from the 8 MHz internal oscillator MightyCore lets you select which serial port you want to use for uploading. UART0 is the default port for all targets, but ATmega324/644/1284 can also use UART1 for upload. If your application doesn't need or require a...

Figure 4-2 shows a block diagram of the Uno R2 with an ATmega16U2 providing the USB interface. The Uno, with an ATmega8, has the same internal functional arrangement as the Uno R2, just with a different MCU serving as the USB interface. Arduino Physical Dimensions Arduino boards come in ...

Internal pull ups are used - switch closed reads as false or 0. Instead of constantly typing digitalRead(PIN) I created subroutines S1() and S2(). If either S1() or S2() are called a closed switch returns 1 or open switch returns 0 - they also update the LCD display. I also wrote...
