Hi !
I’m new to electronics, but now I’ve made a circuit for a sensitive touch sensor to be used with snails. The goal is to have the sensor as sensitive as possible without making false alarms, and at the same time drawing as little current as possible. The motor (M1) should be activated for about 5 seconds. That time can be adjusted by the capasitor (C1) and the resistor (R4).
The circuit I have made seems to work fine on all accounts, except that the activation time vary a lot depending on the state of the battery, due to the battery voltage. That is the problem. I have also made a regular timing circuit using the TS555, but I can’t make that one sensitive enough.
Any suggestions would be highly appreciated!
