Use of java and other languages Hello,
Let's use the ATmega328p as a definition example of a microcontroller. It's widely known and studied, with many web-based tutorials....

Parking project, need help I assume that the lead of the button that is not on D1 is connected to V+.
However, with this wiring, when the button is not pressed, then D1 is floating. Reading D1 could...

<SOLVED> tca9548a i2c multiplexer Wire the AVR's SDA and SCL lines to the master input SDA/SCL on the Multiplexer (Mux). Add the 3.3K ohm pull-up resistors. The Mux gets the AVR's Vcc. (I'll assume...
Relay module 74HC595 Q0 sometimes on Hello,
I recommend that you go back to the very beginning of the design. Because the signal is low-level audio, there is no need to have all the relays-...

I2C and LCD Atmega328p Hello,
In the Master, you are not shifting the Slave's address to the left one bit. This is done so that the bit 0 has either logic low for a write operation or...

Python programming... The AVR is a bit too small to support a minimum development environment during run-time, which is what Python needs.
The 32-bit ARMs, ESP32, and WeMOS do have enough...
