Set your multimeter to measure voltage. Make sure the black measurement lead is connected to the multimeter’s COM socket, and the red measurement lead is connected to the V socket. Touch the tip of the black lead of the multimeter to the negative side of the battery, and touch the red lead to pin 11 on the 4011 NAND-gate IC. You should see a high signal—about 9 V—after clicking the stop button and a low signal—about 0 V—after pushing the start button. If not, check the connections of the SR latch circuit to find the error.”” [Oyvind Nydal Dahl](https://sms4smile.com/quotes/author/oyvind-nydal-dahl/) ## About This Quote This interpretation was drafted with AI assistance.
