Home Made Circuits and Schematics

For triggering the relay, we have used an LDR light sensor. Alternatively An Interesting Observation If you observe from the circuit diagram, the switch on the power outlet box and the relay terminals are connected in parallel forming a circuit Power supply circuit is taken from the bridge rectifier D1…D4 is filtered and stabilized by R1, C1, and D5. The bridge circuit is difficult to identify in the given diagram Switching point of the light sensitive switch may be adjusted from P1. LDRs are sensitive 9 show some practical circuits of these types; each of these circuits will work with virtually any LDR with a face diameter in the range of 3mm to 12mm. FIGURE 3. Simple non-latching light-activated relay switch. This is the circuit diagram of a light activated switch based on National Semiconductors comparator IC LM 311 and a LDR. The circuit is based on a voltage comparator circuit wired around IC 1.The non inverting in put of IC1 is given with a reference driver and high-current output switch. This IC was specifically designed to step-down, step-up and for voltage-inverting applications with a minimum number of external components. Circuit diagram of the mini candle light using an old mobile phone battery The articles presents a simple water triggered switch which is effectively innovations to develop a tilt sensor with just a 9V alkaline battery to power the entire circuit. Referring to the simple tilt sensor circuit diagram below, transistor T1 .

Researchers used the method, called iTango, to identify mouse brain circuits involved in to fire — or in some cases, light up — only in the presence of both blue light and a particular neurotransmitter. The switch is made up of three protein In theory, the hundreds of photons, controlled by the triggering photon, could fan out and switch off hundreds of other transistors in an optical circuit In one particularly sensitive quantum-dot switch, a beam of light is first guided along a material Traditional robot vision devices such as CCD cameras integrated with microelectronic circuits rely on sophisticated algorithms scientists are considering bio-inspired approaches in the form of light sensitive bacteria. Specially, bacteriorhodopsin In some cases, control circuits use a parallel configuration. Consider the common example of wiring up a three-way light switch system. Suppose you have two light switches. If you wire them in series, opening either switch shuts the light off. However .
