The layout to the basic GENIE C08 PIC microcontroller circuit , is seen below.

The following components are required:

Download socket
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.
