Next Shipping Day 3rd December
We are now in the process of moving Technobots 120 miles North to the Town of Rugby. You can still place orders on-line as normal but they will not be dispatched until after we re-open on the 3rd December
Our machine shop is also being re-located so we are unable to carry out machining modifications on gears, sprockets, pulleys etc. Any order placed which includes machining options is unlikely to be processed until mid December.
This kit is available in two variations, this is the light activated switch version or a temperature activated switch is available. The output of the board can be used to control other electronic circuits, turning them on automatically when it goes light, dark, hot or cold.
The board has space for an LED with current limit resistor (both available separately) which will light when the output turns on. The Darlington pair transistor configuration allows an output current of up to ½ an amp to be controlled. Operating voltage 3V to 10V (lower voltages allow for better adjustment of the switching point).
Possible applications include:
- Garden light that switches on automatically at night
- Draw alarm, which sound when a dark draw is opened
- Line following robot (using 2 light activated boards)
- Babies bath over temperature indicator
- Automatic fan
- 1 x 47Kohm potentiometer
- 2 x BC337 NPN transistors
- 1 x miniature LDR (light dependent resistor)
- 1 x 220ohm resistor
- 1 x light activated switch PCB
PCB dimensions: 53mm x 25.5mm.
