Hi all, I'm a new guy from the little island, Singapore. Glad to be in this forum with all the electronics and electrical specialist around.
My problem is as follows:
I have designed a wireless alert circuitry that will generate an alarm signal. I have got my hands on a miniature DC motor as a vibrating alarm but when i wire it to the alarm signal, it doesn't work. Any ideas on why it doesn't work? Also, the alarm signal is an active high signal.
My other problem is with the 3V CR2032 batteries. I have connected 2 batteries is series to obtain a 6V supply. When not connected to any circuit, my multimeter gives a 6V reading, but when I connect the batteries to any load (even a single LED) the voltage drops down to 1.8V. How come the batteries react in such a way and is there any way of making work?
Thanks for taking time to read my problems~
