Design a circuit that emulates an alarm system, which is armed and disarmed with a code consisting of 4 symbols given by the buttons on the board (for example btnC, btnL, btnR, btnU). The alarm is armed or disarmed when the correct code combination is entered. When the alarm is disarmed, LED0 is on, when the alarm is armed, LED15 is on. SW0 is a sensor, when the alarm is armed and SW0 = 1, the LED...

Hello. My MCU is a ATSAMR21E16 of Microchip company. My board was already manufactured and there is only one MCU as CPU. I am going to look over the boot load method using USB port which is directly connected to the MCU. Of course, I have a main firmware and if you can deliver the code of USB bootloader, then I will combine them. Regards.
when the phone is connected to the phone fan will work in the port will charge the phone will receive a sound
