|The layout to the basic
GENIE C08 PIC microcontroller circuit , is seen below.
The following components are required:
4.5 to 6 volt power supply
Resistors - Two resistors - 100k, 22k and 100k.
ADDING AN INPUT
Adding and input requires further connections, as seen below.
A push switch is added, with a 10k resistor, connecting to the 0v rail. There is also a connection to the +v rail.
Further inputs can be added in the same way.
ADDING AN OUTPUT
Outputs are added by simply connecting from an output, such as G4/A, to a component such as an LED. A 330R resistor is included, to protect the LED.
|A low voltage solar motor can be added to an output directly. However, standard motors of 3v or over, should be connected as shown below. Additional components include a 1k resistor, MPSA14 NPN transistor and a IN4001 diode.|
|A relay can be added in
exactly the same way as a standard motor, see below. This allows a
secondary circuit, with a more powerful power source, to be added.
The GENIE C08 (below), controls a relay from output A/G2. When this output is ‘high’ or ‘on’, the relay energises and the secondary circuit drives a powerful 12v motor.
