NE555 generator emits fixed frequency sound

Overview

Use the NE555 fixed frequency generator to emit sounds of different frequencies through different resistances, and adjust the 555 transmitter to emit different sounds through different tissues, such as do, re, mi, fa, so, la, xi and other different frequencies. However, Due to a slight error in the selected resistor, the sound frequency is not very accurate.

msp430f4152 TimerA emulates UART
[i=s]This post was last edited by 18633013902 on 2016-5-31 15:51[/i] The main feature of this program is that different timers are used for sending and receiving. I just came across this problem and c
Ask about u-boot transplantation
I used the Liyutai armsys44b0-p board and followed the instructions on the Internet to modify the compilation and start the operation. The results are as follows: U-Boot 1.1.6 (Oct 15 2008 - 10:41:03)
A question about the power supply circuit
The transformer outputs two 18V lines (3 wires in total), which pass through the rectifier bridge and electrolytic capacitors, and then power 7812 and 7912 respectively. Now the problem is that the vo

Two weird questions
Question 1: I made a 2410 baseboard by myself, and bought the core board. I connected one side of the buffer chip 74245 on the baseboard to the data line (md0-md7) of the core board, and the other sid
Admin, am I demoted?
I haven't logged in for a long time. When I came back, I saw a lot of notifications. I clicked on one and was shocked. Was I downgraded? I was at the intermediate level a year ago, so how come I'm dow
