Hi,Making a simple tester for automotive. R3/R4 are 100K and cause TestLead to have 6V. If TestLead is touched to a ground wire, an Arduino picks up the voltage drop at ADC and starts the test. Q1A is turned on and power flows from +12V through R1 load resistor and Q1A to vehicle ground through TestLead. Arduino monitors voltage at ADC and generates a pass/fail for the ground circuit under test.

Suppose I have chosen a capacitance value for a DC block capacitor. How can I determine the required DC voltage of the capacitor? Should it be based on the average, RMS, or peak voltage? For example, if I am transmitting at 400W, what DC voltage value should i choose? Additionally, if the RF line also carries a DC voltage along with the RF signal, will the required DC voltage of the capacitor be different?

While it may not seem like it, it has almost been a century since the first touch controller was created. Since then, touchscreens have become an integral part of our everyday lives, informing our interactions with our phones and tablets, automobiles, and even our dishwashers. Microchip Technology has recently introduced the new MTCH2120 to its portfolio of capacitive touch controllers to give designers a turnkey method for implementing these touchscreen devices into our modern-day ecosystem.
