step by step. First, familiarise yourself with the hardware functions and start your own
programmes only after this.
In the first test, you will start small programmes that are already finished in the controller. The
associated programme lists provide an initial impression of the options. They are only briefly
explained. The precise explanation of the individual commands follows in the next chapter.
For the first test, set up only the basic configuration with the controller and the required
additional elements on the pinboard. You need:
• Connection of the voltage supply at GND (minus) and VCC (plus)
• A blocking capacitor 100 nF between VCC and GND
• Reset resistor downstream of VCC and reset capacitor downstream of GND
• Oscillator resistor 100 kO downstream of VCC and capacitor downstream of GND
The microcontroller HT46F47 is operated with its internal RC-oscillator. The resistor at the Osc1
input specifies the cycle frequency. 100 kO sets a frequency of approx. 2 MHz. On demand, you
can work with lower or faster speeds. The connected capacitor serves only to block and has no
influence on the cycle frequency. The connection Osc2 remains free. On demand, you can
connect an additional resistor against VCC here and disconnect impulses with a quarter of the
cycle frequency.

Use the upper and lower supply rails on the pinboard as ground connection GND. Here, the
black cable of the battery compartment, i.e. the minus pole, is connected. The plus line VCC is
connect to the red connection cable of the battery compartment. Wrong polarity must be avoided
