Motion detection is an important part of security system and PIR sensor is one of the most commonly used sensors to trigger alarm when motion is detected. This sensor can easily detect the motion of p...
A while ago, I happened to see the registration for the Digi-Key Innovation Design Competition, and I took part in it with the mentality of giving it a try. Fortunately, I was selected in the first ba...
Now we need to add debugging tools. Previously, we had to modify the program, burn it, modify it again, and burn it again, which was very inefficient.
Now with Shell, you can directly enter the comman...
I work in a small company in Wuhan. I was originally engaged in hardware work. After graduating and working for a year, I felt that the work of a hardware engineer was too painful, so I began to turn ...

Method 1:
Give the circuit a square wave signal, and use an oscilloscope to observe the square wave signal, from which you can obtain certain frequency response characteristics.
Method 2: ...[Details]
It should be noted that TXD and RXD refer to themselves, so the two should be connected using a cross serial port, otherwise there will be no data.
In addition, the TXD of one MCU 1 can be connecte...[Details]
As the name implies, a stop-start system shuts off the engine when you stop, rather than idling it, and then quickly restarts it when you need to go. If you need to drive a lot, this can reduce emiss...[Details]
