It should be around 4 to 5V, and not higher than 5V (for a high). It also should not go negative. Something like this will protect the input pin: Warning - audio from an audio jack will be AC and it will go negative.

WebThe frequencies used for RFID systems are typically in the range of 125 kHz to 13.56 MHz. To block RFID chips, a device that emits a signal at the same frequency as the RFID system can be used. However, it is important to note that the use of such devices may not be legal in all situations. Can RFID be intercepted? WebYou'd have to find a factorization that satisfies these constraints. Let's see an example, you'd want a 2.3 seconds delay. Note that 2.3s is the period, not the frequency, so you'd need to put its inverse into the formula. (PSC+1) * (ARR+1) = 84000000 / (1 / 2.3) = 84000000 * 2.3 = 193200000 chiswick glass
