Alarm Sensor

Alarm Sensor PUBLIC

How it works? 1. The RESET switch is OFF in the Alarm Sensor to operate. 2. Any object that triggered the sensor [SWITCH, push to off] it will charge the capacitor [C1]. 3. When the charge at the C1...

Experiment 11 (part 1) from Make: Electronics by Platt

Experiment 11 (part 1) from Make: Electronics by Platt PUBLIC

My attempt at simulating the beginning of experiment 11 from Make: Electronics by Platt. The LED should blink. I am not sure why it isn't working and could use some help in determining the problem.
